Hello, Miklos!
I can't reproduce this on host 2.6.28.7 with uml guest of current git.
Have you tried 2.6.28.7? Does it have the same problem?
Thanks.

Yes, still present in latest stable 2.6.28.5
I updated the report to say that this happened on my 5 year old Pentium 4, but now I got a new Dell desktop (Intel G45 based) and the exact same problem happens, so I can't be the only one seeing it. In the bugzilla Eric Anholt said that it could be related to vblank and that jbarnes had look into a similar issue before, so maybe he has some clue.
Thanks.

The fix for this has landed in mainline as commit 02ac59 for ext3, and
commit 9eddac for ext4.
Rafael, I've marked the bug closed in BZ for your convenience.

I'm still seeing this on .29-rc5, and I think that my bug #12263 is a
duplicate of bug #12609,
or more correctly it's a duplicate of mine because I reported first.
It seems like the bug has been fixed in tip/master for some time now.
Below is the diff of origin and tip from when I tested.

This one, done on Jan 10, more than a month ago:
f1d26da: Revert "libata: Add 32bit PIO support"
When a commit causes trouble in -tip qa i immediately revert it in 95%
of the cases, no questions asked. Especially if it's related to
persistent storage.

OK, thanks.
We seem to have a working fix patch for this issue in bug #12609.

Wait, if this is indeed post-2.6.27 regression, it couldn't possibly have
been caused by that patch which got merged during 2.6.29-rc1 timeframe.
Something's up with this bug...

SATA uses the SCSI layer, right? It could then perhaps be these bits in
tip:out-of-tree:
813104e: Revert "[SCSI] simplify scsi_io_completion()"
84db545: Revert "[SCSI] Fix uninitialized variable error in scsi_io_completion"
0eb6038: Revert "[SCSI] Fix error handling for DIF/DIX"
3cd94dd: Revert "[SCSI] scsi_lib: don't decrement busy counters when inserting commands"
c27aed5: Revert "[SCSI] scsi_lib: fix DID_RESET status problems"
i needed these to keep an aic7xxx box from crashing. This regression got
introduced at around 2.6.28-rc1, so it fits the timeframe.

Also, it's been reported for a hard disk while regression in bug 12609
only hits the ATAPI devices. I think that bug 12263 needs to be reopened.

After referring to the SCSI command codes "cdb 0x1e" means ALLOW MEDIUM
REMOVAL command -- which could hardly be addressed to an usual hard disk. So,
it looks like we had a case of the confused bug report which has a lot of info
on the hard disk while errors were most probably happening with a CD/DVD
drive. :-)

Yes, I originally thought it was my hard disk because the kernel logs showed ata2.
But, Tejun Heo figured out it was my DVD drive (ATAPI) that was on the ata2 link.
(see http://marc.info/?l=linux-kernel&m=122993014109646&w=2)
I tried to bisect it, but around .28-rc1 I began to get numerous compile errors, so couldn't continue.
I also tried patches that Tejun sent me, but non of them worked, it just slightly change the error message.
So, yes this is a regression that was introduced in the .28 merge window, and I still think that bug #12609 is a duplicate of my bug.
I don't see this bug on tip/master and this is the diff of origin and tip at the time I tested.

If 12609 is truly a post-2.6.28 regression and 12263 is post-2.6.27
regresssion, this just cannot be.

Maybe the reporter of #12609 didn't notice/test kernels 28-rc1 to 28. Or
maybe the difference in hardware is
the issue, but the bug is still the same. Don't know.

Sorry Justin, you must be confused: as Sergei says,
#12609 and #12263 can only be different.
I was one of the reporters of #12609, and I do know it's a post-2.6.28
regression (and Larry said so too), and one fix (not the preferred fix)
is to revert the ata_bmdma32_port_ops from 2.6.29-rc, and the preferred
fix is to improve the ata_sff_data_xfer32() introduced in 2.6.29-rc1.
2.6.28 does not contain any ata_bmdma32_port_ops, nor ata_sff_data_xfer32(),
not did 2.6.28-rc1 contain them. So it is impossible for the reversion of
the patch that introduced them to fix any problem on 2.6.28.
I'm quite prepared to believe that your #12263 manifests similarly to
#12609, and that a tip tree which contains a fix for #12609 contains
a fix for #12263; but please, those bugs are not the same, and they
don't have the same fix.

Well, like I said: "[I] Don't know". I'm not a kernel developer (or even
any developer... yet).
I'm just someone that tests the -rc kernels to see if there's any
problems with my hardware.
I try to report any regressions to lkml, and hopefully help the developers.
To me, who has no knowledge of all these low level issues, the following
error messages
look strikingly similar with a quick glance.

So, will the patch for 12609 fix my issue also, or does there need to be

Note the different value of the status, error and interrupt reason
registers: 51/20:03 vs 50/00:01. The former means (unexpected?) status
phase interrupt with error indication and the sense key NOT READY, the
latter means (unexpected?) command phase interrupt with no error. IIUC,
the former happens once the 'sr' driver first sends the TEST UNIT READY
command while probing the CD/DVD drive, the latter seems to be a result
of some polling process (originated from userland) -- I'm not seeing
ALLOW_MEDIUM_REMOVAL anywhere in this driver. So they only look similar,
I think...

Most probably it'll need another patch.

And that is why I'm a tester and you're a developer ;) Thanks for the
info! Next time I'll look closer
and maybe know what I'm actually looking at.

So then, #12263 should be reopened and marked as not a duplicate.
Anyways, if tip/master gets merged how it is now then my bug should be
fixed.

This one sounded like a configuration error.

I think if it works without DRI in 2.6.27 and doesn't work in 2.6.28,
it isn't a configuration error, but a real regression.

It only worked by accident without DRM support, since you were using the
ATI codepath in the firmware rather than the Intel one. That bug's been
fixed, so now you're following the Intel codepath - unfortunately
there's no way to do that without kernel-level graphics support, which
means DRM.

Tino, does it all work fine if CONFIG_DRM is enabled?

Yes, this should still be listed.
I just tested against 2.6.29-rc5 and the problem is as bad as ever
(perhaps worse?)
--- hermes-old.wumi.org.au ping statistics ---
900 packets transmitted, 448 received, +317 errors, 50% packet loss, time 899845ms
rtt min/avg/max/mdev = 0.131/420.015/10890.699/1297.022 ms, pipe 11
The guest being pinged crashed during the test - the QEMU monitor was
accessible, but the guest didn't respond to "sendkey alt-sysrq-s", etc.
This was the last thing in the guest syslog after reboot:

I think I saw some patches to fix the latency tracer for non-RT tasks on
the mailing list a while ago. If that's still going to be a useful test,
can someone give me some hints on which kernel tree and/or patches to
download to get that working? The simpler you can make it, the better ;)
Cheers,
Kevin.

i looked at the trace you did earlier and which you uploaded to:

qemu-sy-4237 has been scheduled away, and the system appeared to have done
nothing in the meantime. That's not something that really looks like a
scheduler regression - there is nothing the scheduler can do if KVM
decides to block a task.
It would be nice to enhance this single-CPU trace some more - to more
surgically see what is going on. Firstly, absolute timestamps would be
nice:
echo funcgraph-abstime > trace_options
echo funcgraph-proc > trace_options
as it's a bit hard to see the global timescale of events.
Secondly, not all events are included - in particular i dont really see
the points when packets are passed. Would it be possible to add a tracing
hypercall so that the guest kernel can inject trace events that can be seen
on the native-side trace? Regarding ping latencies really just two things
matter: the loopback network device's rx and tx path. We should trace the
outgoing sequence number and the incoming sequence number of IP packets,
and inject that to the host side. This way we can correlate the delays
precisely.

I was going to try and grab the trace with absolute timestamps tonight,
but that option doesn't seem to be available in Linus' current kernel.

(replying here too - replied in the bugzilla already)
that's a feature of the latest tracing tree, so if you try -tip
you'll have it.

Okay, here's some more trace data. I grabbed a few samples at different
times during the ping test. I think the data in files trace6.txt and
trace8.txt coincided with some of the biggest delays.
http://disenchant.net/tmp/bug-12465/trace-2/
This is captured on 2.6.29-rc5-tip-02057-gaad11ad. The kvm guest being
pinged is process 11211:
flexo:~# pstree -p 11211
qemu-system-x86(11211)─┬─{qemu-system-x86}(11212)
├─{qemu-system-x86}(11213)
└─{qemu-system-x86}(11609)
Cheers,
Kevin.

I'm not convinced its as fast as it should be on 2.6.27.
I'm currently testing 2.6.27.14 hosts on several different pieces of
hardware with a common 2.6.23.17 guest.
Currently the UML guest on my desktop machine which is an 11 year old
300Mhz dual-processor Pentium-II with 256MB of RAM running 2.6.22.14
is giving a rather sound performance drubbing to the identical UML
guest running on a 2.5GHZ dual-quad 5420 with 16GB of RAM running a
32-bit 2.6.27.14.

I did a bisection, and this is the commit which is responsible:
commit 464b75273f64be7c81fee975bd6ca9593df3427b
Author: Peter Zijlstra <a.p.zijlstra@chello.nl>
Date: Fri Oct 24 11:06:15 2008 +0200
sched: re-instate vruntime based wakeup preemption
The advantage is that vruntime based wakeup preemption has a better
conceptual model. Here wakeup_gran = 0 means: preempt when 'fair'.
Therefore wakeup_gran is the granularity of unfairness we allow in order
to make progress.

If that commit is responsible, then it should also be very slow in pre
28 kernels, where the same exists. Hm, there's another possibility.
Can you try echo NO_LAST_BUDDY > /sys/kernel/debug/sched_features?

Everything prior to 2.6.28 was fine in this respect, so there must be
some subtle difference.

It didn't help, unfortunately.
Applying this patch on top of latest git (which essentially reverts
the above commit) fixes the slowness.

I'm happy to hear that actually.

We definitely don't want to do that. Hm. There are only two commits
that spring to mind...
1af5f730fc1bf7c62ec9fb2d307206e18bf40a69, which is another hope not, and
3f3a490480d8ab96e0fe30a41f80f14e6a0c579d which doesn't seem likely.

This can't be reverted on latest git.
Is there a way to trace what is happening in the scheduler?
Thanks,

Sure. Ingo has a script for gathering info (attached), if you run it,
please gzip up the output and send me a copy offline to eyeball.
There's also ftrace, but I've not tried that yet, so can't offer any
advice, I use primitive but effective time_after() + printk() with klogd
wakeup disabled (deadlock).

btw., there's a recent commit:
32a7600: printk: make printk more robust by not allowing recursion
since then printk shouldnt deadlock anymore, even if called from within
the scheduler.
Btw., ftrace_printk() can be used similarly (and you can capture it
nonstop via /debug/tracing/trace_pipe), and should not deadlock either.

How's 27? That code basically makes .28 do what .27 did, we tried
something else for a little while and that made stuff suck rocks.
