PC(see below) 256Mib of RAM, linux-2.6.2, 300Mib swap file (swapon /mnt/swap/swap)
When programs cause big memory usage i have this

As in /usr/src/linux/REPORTING-BUGS:
- keyword:
kernel memory manager
- version (cat /proc/version):
Linux version 2.6.2 (root@gluon) (gcc version 3.3.3 20040125 (prerelease) (Debian)) #2 SMP Thu Feb 5 03:45:58 EET 2004
- A small shell script or example program which triggers the
problem (if possible)
load gimp, sodipodi (graphic editors) and work for some hours
- output of ./scripts/ver_linux:
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

Can you reproduce the problem without proprietary drivers loaded ?

[ helpful info snipped ]
Interesting, thank you. That's the second report (first on 16 Jan,
and in that case Not Tainted). I looked around and found some bugs in
the swapfile page accounting (if swapfile filesystem blocksize < 4k:
is yours? never heard back from Marcel on that) - still intermittently
working on and testing the fixes there - but in the end nothing which
would actually cause this BUG. Was rather thinking it came from slab
corruption, but a second report makes that (a little) less likely.
I'll look again later on, but other eyes may find it sooner.
Hugh

oops, i thought i told you that my blocksize is exactly 4k - sorry
btw, i hit this bug again a few days after i reported it
one time it went crazy and oopsed 8 times in about 8 minutes
i think it only happened when the system was swapping heavily
(swapd creating new swapfiles as fast as it could) and i manually
swapon'ed another (bigger, ~50MB) swapfile by hand

I'd remove all /lib/modules/2.6.2/, reboot my box, `swapon
/mnt/swap/swap`, gimp, gqview, and: see attach syslog_no_modules.txt
(it's "Tainted: G S"), my .config is in attach my_kconfig.txt (grep -e =y /usr/src/linux/.config > my_kconfig.txt)

I had "Tained: XFS". I have (as You can see) rootfs on xfs, i removed swap file,
i cheked /dev/hda1 completely via xfs_check, made swap via dd. That didn't help.
