Jan Ischebeck <[email protected]>
I think there is a memory leak on some part, but I dont know a damn
about kernel.
I have a similar problem with 2.6.1-mm1 and previous kernels, I'm
testing mm2 right now and still no problem, using vmware and nvidia.o
modules, but have an uptime of 5:30 hrs. so I need to wait some more
time, usually the kernel starts eating RAM and the hangs when swap start
to play because of the lack or "real" RAM.
here is a dmesg that I could get before one of those hangs
I dont know how to trace the error

I'm seeing this also. Started in 2.6.1-mm1 with the debug change to
list.h I've got a fairly repeatable case I can create:
Bring computer up and let it run a while - 1 hour or so. Start rsync
process to backup system. This seems to trip it almost every time. If I
boot directly into runlevel 1 and immediately do the same rsync backup,
it will work fine.
When I first hit it, I had preemption enabled. I re-compiled without it,
and it made no difference.

Hi Jan,
I guess you are getting this without tainters also.
Can you give some more details like .config, what filesystems
you have etc.
Thanks

Hi Maneesh,
I've tried here my fstab:
/dev/hda3 / ext3 defaults,errors=remount-ro 0 1
/dev/hda8 none swap sw 0 0
/dev/hda9 none swap sw 0 0
/dev/hda6 /home ext3 defaults,errors=remount-ro
/dev/hda2 /dos ntfs defaults
/dev/hda5 /dos2 vfat defaults,user
/dev/hda7 /dos3 vfat defaults,user
proc /proc proc defaults 0 0
sysfs /sys sysfs
/dev/fd0 /floppy auto defaults,user,noauto 0 0
/dev/cdrom /cdrom iso9660 defaults,utf8,ro,user,noauto
/dev/cdroms/cdrom1 /cdrw iso9660 defaults,utf8,ro,user,noauto
The .config, a list of loaded modules, lspci and a 2.6.1-mm2 dmesg
output are attached.
As you see from the dmesg, there are some other problems too, like
AGPGART, ATKBD and USB sometimes reconnecting devices (USB Mouse), but I
don't think that they are related with the above bug.
If you need more stuff, or want to test a patch, please tell me.

Hi Walt,
This patch is needed for a different race. We get hangs when we read and
remove a sysfs directory at the same time on an SMP box. It is easily
recreated by running following two loops. (Obviously without this fix)
while true; do insmod drivers/net/dummy.ko; rmmod dummy; done
while true; do find /sys/class/net > /dev/null; done
I am still not convinced that this fix will cause any problem.
The kswapd problem what I have understood so far, is happening because of a
bad d_child pointer in the dentry. As it is hitting the list_del BUG(), and the
only list_del in prune_dcache() is for d_child list pointer. I suspect dentry
from d_child list is being deleted more than once.
Can you elaborate on the recreation scenario a little bit more or if possible
run this debug patch on top of -mm3. This should print some info about the
bad dentry.
Thanks
Maneesh

Hi Walt,
One more thing I wanted to ask you is that whether you unload any module/driver
in the system. Because unloading a module will cause the corresponding
sysfs directory from the system through sysfs_remove_dir_call(). Or any other
activities with sysfs filesystem.
Thanks
Maneesh

Walt,
Pleae run this debug patch instead of the previous one. Thanks to Andrew
for suggestion.

OK. I've got -mm3 with this debug patch running now. Hopefully this will
give us more info.
My workload that causes this bug most readily to appear is:
Use the computer system for a few hours. Compile some apps, surf, email
etc... At the end of the day, I typically shut down the system to
runlevel 1 to back it up. I've got a 2 disk md raid0 array that is my
primary working array, which I then backup to a 2 disk device mapper
raid0 array. An rsync from the primary to the secondary usually trips
the bug. If I boot the system and immediately do the rsync, it will
complete. It takes a period of uptime to trigger.
I've got a rather lengthy compile process now, so will try the rsync
after work and report on any debug success (rsync failures). Thanks,
-Walt
