[parisc-linux] SMP (in)stability

[parisc-linux] SMP (in)stability

[Jeremy Drake]

After having read on this list that some SMP-related problems were fixed,
I decided to try out the latest kernel as SMP on my J5k.  I tried my old
test, apt-get update, on it.  It downloaded the package lists fine, but
stopped after printing "Reading Package Lists... 0%".  Since I was running
over an ssh session, I don't have any console log messages that may have
appeared, but every time before this (on older smp kernels) it has stopped
at an unaligned access message.  As a point of reference, the last smp 
kernel that was stable for me was 2.4.17-32-smp in debian.  There was an 
updated version of it that was not stable, the stable one was the release 
before (if the box was up, I could get more info from the .deb I grabbed 
of it).  Hopefully that info will help you figure out what change was 
likely to have caused the problems.  I'll get you specifics on that kernel 
package tomorrow.

It Works For Me. (tm)

Did you build this kernel yourself or grab a debian kernel package?
Can you provide "uname -a" output of the SMP kernel you tested?

FYI, I've uploaded my a500 build (should work on j5k as well
if it's using serial console) to:
	ftp://ftp.parisc-linux.org/kernels/a500/2.4.18-pa52.tgz

The -pa52 kernel built 100+ kernels/modules successively until
I stopped it on the a500-44. The same kernel on a500-6X (PA8700)
crashes after 12 or so hours of building gcc bits. I've also seen
eth0 (tulip driver) spontaneously go to an unconfigured state
without saying anything on the console. It's possible a cron job
or something else ifdown'd it but I don't know why.

BTW, before I go to bed tonight, I expect the latest kernel to be -pa54.
I'll be adding a one-liner sym53c8xx_2 driver patch to allow one to
use the default CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE=1.
One can use sym53c8xx_2 now with CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE=0.
Richard Hirst and Paul Bame (and a few others) have tested this out already.

thanks,

Oops, I thought I said -pa52.  This is built from the cvs.parisc-linux.org
tree.  I won't be able to get the actual output of uname -a until
tomorrow, but I can guess what it will say: "Linux krakatoa 2.4.18-pa52
SMP #X Tues July 09 14:30:00 PDT 2002 parisc unknown".  Not too sure what
it says for the arch...  I sent my uniproc .config to the list earlier
today, but I can send you the smp one tomorrow if you want it.  I can even
send you the package that make-kpkg made for me, if you want.

I don't really understand what the deal is with SMP on this box, but 
various strange things happen: apt-get update kills it, samba kills it, 
and if I just leave it alone, it dies by itself after a while (I only 
witnessed the apt-get problem with this particular kernel).  I can build 
the kernel happily on it, it's just those certain things that crash it, 
usually after spitting an unaligned access message to the console, and 
sometimes causing an HPMC (the last one I remember was a "runway broad 
error").  I would chalk it up to hardware, because this box has a broken 
onboard USB connector (one is physically damaged and the other quit 
working when the pins in the damaged one got bent around), but I pulled 
the drive and stuck it in another J5k that is not damaged, and is 
virtually identical in configuration to the one I usually use, and it did 
the same thing.

Uniproc is perfectly stable, I have not ever seen it crash.  I just don't
like to let hardware sit unused like that second proc does.  (i have a
486sx25 running linux that I write emails on in pine, and a 286 running
dos and windows 3.1 sitting here on my KVM switch...;)

I will look at the tgz and also cvs update tomorrow when I get in the same 
building with the box, and send uname -a and .config, and also any 
observations I can make of the box when I get to it (any messages on the 
LCD, any ser pim output that it may have, any log messages)...  Next time 
I'll leave a serial console open to it :)

We have pa51 running on J5k:
Linux mkhppa02 2.4.18-pa51 #1 SMP Mon Jul 8 12:43:59 CEST 2002 parisc64 
unknown

It's a custom build from cvs (see .config attached).

The box worked perfectly fine with 2 setis running on it during 5 days 
with pa46,
and now it's been updated and running for 2 days in the same conditions.
So does our A500 under heavy load, which used to crash a couple of hours
after being started with kernels < pa46, when running seti/dnetc and 
building ISOs.

It also seems to me (though i cannot confirm atm) that the 'PIO mode' in
SYM53C8XX driver improves stability.

About J5k, the only thing quite curious is the message that appears on 
the LCD after boot:

We first have 'Linux 2.4.18-pa5' (the name is too long and doesn't fit 
the display)
and then a PDC code overlap on it:
'INI CC01';
which gives us (iirc) something like:
'INI CC014.18-pa5'

echo whatever > /proc/pdc/lcd doesn't get annoyed by this message, so it
occurs only after boot sequence.

I'm building a pa54 ISO/Lifimage that will be available soon at ESIEE 
and on ftp.p-l.o :)

I always use sym-2 now, because I had this strange harddisk slow down problem
with the old sym driver. That might be worth a try, too.

Well, we were using sym-2 on A500 before switching to sym-1, and at that=20=

time it
used to hang very often...

By the way, if you want to take a look at what I reported to Ryan when=20=

hangs
occured (SysRq 't', Ryan modified), take a look at:
http://pateam.esiee.fr/archive/mails/

and read the *SMPHangReport* files...

Talking about which; something weird happened:
we got a couple of segfault on previous ISOs build, but relaunching the=20=

build was enough to solve the problem.
Here I got something quite more subtle:

a make process (11859) seems to be stuck (running for about 2hours),=20
though seen as 'running', and the machine did not hang.
ctrl-c was enough to stop it...

I have no idea whether it's related to SMP pb we're tracking down=20
anyway...

The address it is trying to store to is 0x10112738, which is kernel
_code_ space.

void remove_wait_queue(wait_queue_head_t *q, wait_queue_t * wait)

so either r25 (= wait) is wrong, or the wait_queue_t it points at is
corrupt.  r25 is 0x3....... don't know what is up there; vmalloc'ed
memory?

In hacking gcc this morning trying to fix a bug in loading 64-bit
constants, I seem to have achieved a state where the gcc build crashes
gsyprf11 in a deterministic manner.  It's gone down three times.
It only takes a few seconds after the build starts for the machine
to crash.

Moving the code to hpux11, this is the error that causes the crash:

hrm.  i wonder what happens when we run off the top of the stack ...

we seem to handle this properly at least most of the time.

i have tried various recursive function call cases and at least simple
tests don't crash the system (we just get a segfault)

The LCD screen reads "OFF 0000:".  This is a new one for me :)

 Description: 32 bit SMP Linux kernel image for version 2.4.17 on HPPA.
  This package contains the 32 bit SMP Linux kernel image for version
  2.4.17 on HPPA, the corresponding System.map file, and the modules built
  by the packager.  It also contains scripts that try to ensure that the
  system is not left in a unbootable state after an update.
  .
  Kernel image packages are generally produced using kernel-package,
  and it is suggested that you install that package if you wish to
  create a custom kernel.

The log just stops and picks up again when I rebooted.

You can get the .deb for the smp kernel that I build from 
http://linux.apptechsys.com/~jeremyd/kernel-image-2.4.18-pa53_jeremyd.200207091430.smp_hppa.deb

Here's the output of ser pim for the one that has the right date/time 
stamp.  Looks like another "runway broad error" -- broad seems to be short 
for broadcast.

-- 
	NEW YORK-- Kraft Foods, Inc. announced today that its board of
directors unanimously rejected the $11 billion takeover bid by Philip
Morris and Co. A Kraft spokesman stated in a press conference that the
offer was rejected because the $90-per-share bid did not reflect the
true value of the company.
	Wall Street insiders, however, tell quite a different story.
Apparently, the Kraft board of directors had all but signed the takeover
agreement when they learned of Philip Morris' marketing plans for one of
their major Middle East subsidiaries.  To a person, the board voted to
reject the bid when they discovered that the tobacco giant intended to
reorganize Israeli Cheddar, Ltd., and name the new company Cheeses of Nazareth.

I tested -pa53 on smp on J5k building kernels (make -j4), built 115,
here's a sample start/stop time. 
Start: Sat Jul 13 19:23:25 PDT 2002

It is just apt-get update and samba (so far) that kill it.  Just did a cvs
update, worked fine.  I wonder what it is about apt-get that kills it.  
Can someone else with a J5k test this?  Running a current 2.4.18 smp
kernel and running apt-get update.
