Will appear sometime at
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.67/2.5.67-mm1/
. sparc64 is now using gcc-3.x, so there is a patch here to make gcc-2.95
the minimum required version.
. A few rmap-speedup patches reduce the rmap CPU tax by 25-30% on a P4
. Various other cleaups, speedups and fixups.

This is fine. The changelog comment doesn't look right though. It says
it's inferrable from slabinfo; it's meant to measure the number of
reverse mappings performed, or aggregate faulted-in virtualspace on the
system, or the number of PTE's pointing at userspace data.
The internal fragmentation within slabs is a separate notion.
pte_chains carry more than a single pointer, so the net utilization and
internal fragmentation of the things allocated can be computed from
nr_reverse_maps/(#pte_chains * NR_PTE), and is very different from the
internal fragmentation of slabs (there is no relationship whatsoever).
This stuff has been disturbed on several occasions, and effectively
lost whatever meaning it had left after PG_direct anyway, regardless
of who changed it to mean what, as the accounting was never adjusted to
remove PG_direct reverse mappings (the actions, not any kind of space)
from the count due to not being able to identify the notion that would
be measured by it. nr_shared_reverse_maps? It's dead, kill it.

Hi,
This does not boot here. I loop with the following message.
i8042.c: Can't get irq 12 for AUX, unregistering the port.
irq 12 is used (correctly) by my 20267 ide card. My mouse is
usb and AUX is not used.
Ideas?

task_vsize() mysteriously appeared on my profiles. This should remove
it from them by using the already in-use elsewhere for rlimit checks
mm->total_vm for the benefit of O(1) cachelines touched.

I guess that's due to my early kbd init patch.
So why do you have i8042 configured into your kernel?
The loop doesn't terminate? Do you get the same message (above)
over and over again?

Yes, until I trigger a reboot (SysReq+B).

And does reverting

Interesting. If I force that register IRQ 12 to fail, I just get this
one time:
i8042.c: Can't get irq 12 for AUX, unregistering the port.
serio: i8042 AUX port at 0x60,0x64 irq 12
serio: i8042 KBD port at 0x60,0x64 irq 1
Just saw Andrew's email...

Just to confirm, removing the above patch lets me
boot just fine.

Devfs fails to find all partitions with 2.5.67-mm1, plain 2.5.67 is fine
I have 2 scsi disks, and 2.5.67-mm1 find only some of the partitions
when I boot. Below is ls -l listings for /dev/discs/disc0 and
/dev/discs/disc1. Note the missing stuff - linux wasn't at all
happy when the device for /usr couldn't be found at boot time.
Running cfdisk showed that the partitions were there though.

2.5.67 works with framebuffer console, 2.5.67-mm1 dies before activating
graphichs mode on two different machines:
smp with matroxfb, also using a patch that makes matroxfb work in 2.5
up with radeonfb, also using patches that fixes the broken devfs in mm1.
I use devfs and preempt in both cases, and monolithic kernels without module
support.
2.5.67-mm1 works if I drop framebuffer support completely.
Here is the printed backtrace for the radeon case, the matrox case was
similiar:

Well, bugs were fixed since 2.5.67-mm1. Just upgrade to the most recent
kernel (2.5.70-mm1).

2.5.69-mm8 is fine, 2.5.67-mm1 dies before mounting anything read-write.
The early kernel boot is fine, the penguin appear,
a bunch of the usual messages scroll by too fast to read,
and then it hangs.
The kernel is UP, with preempt & devfs. All filesystems
are ext2. This kernel has no module support.

This is unusual; I'm having trouble very close to this area. There is
a remote chance it could be the same problem.
Could you log this to serial and get the rest of the oops/BUG? If it's
where I think it is, I've been looking at end_page_writeback() and so
might have an idea or two.

I tried 2.5.70-mm1 on the dual celeron at home. This one has
scsi instead of ide, so I guess it is a RAID-1 problem.
This machine has root on raid-1 too. I believe there where
several oopses in a row, I captured all of the last one
thanks to a framebuffer with a small font. Here it is:
Unable to handle kernel paging request at virtual address 8a8a8ab6

This looks very similiar to the partial trace
from the ide machine,
it had everything from _end_that_request_first
down to the three default_idles, but with ide
instead of scsi functions.

That's POISON_BEFORE: "use of uninitialised memory", not "use of freed
memory".
I fiddled with the slab poisoning values, and shall undo that.

I'm having a similar problem here with 2.5.70. I can't
seem to get the entire stack trace though, but with a
stripped down kernel config it seems to be when during
the time MD starts working.
Machine is an asus p4c8000, intel ich5, using the IDE
part not sata. I'm also using /dev/md0 as my root
partition.
Hope that helps, i'm trying to find a null modem to
get a real capture ;).

Greetings all.
I think this might fix the bug, but I haven't looked very closely
yet. I will expore it more deeply when I get time.

How does the following patch look for the double free.

I've finally gotten 2.5.70-mm1 compiled and bootable on my system, but
with my /home being RAID1, I was getting crashes that looked alot like
this as well. This was a Dual PIII Xeon 550, with a mix of IDE and
SCSI drives. /home was on a pair of 18gb SCSI disks, RAID1.
I also had problems with the new AIC7xxx driver and had to drop back
to the old one to get a boot. I think. Lots and lots of confusion
here.

Thanks. It is a good start, but there are other problems with freeing
things on error paths. This patch should fix it all.
NeilBrown
--------------------------------------------
Fix up freeing of kmalloc structures
Some paths free things twice, others free un-initialised values :-(
Not any more.
