Subject: 2.6.22-rc3 : "BUG: scheduling while atomic: swapper/0x00000100/0"

Hi,
The stock 2.6.22-rc3 (with no alien modules or patchs) on my i386 desktops
fired this message in loop like a mad (thousands of times/second) until
reboot, for no evident reason (I mean, I don't know what I did to get this,
from an end-user perspective : I was just editing text on vim and surfing
the web with firefox).

The same kernel worked for several days without exposing surch a problem
and this never occured with the olders kernels I used (2.6.17, 2.6.21).

Beside the log presure, the only symptom I noted is that reboot didn't work:
it killed X and probably most userland, but got silently stuck on the console,
without actually restarting the machine. Then, on the console, everytime I
typed a key, 2 new "BUG: scheduling ..." lines appeared. Typing ctrl-alt-del
finaly forced it to physically reboot.

I've got more details in dmesg. Sample (full dmesg plus more
at http://oshima.zouh.org/~ben/2.6.23-rc3_bug_details.txt):

Since I see the word "time" there : note I have NO_HZ, HIGH_RES_TIMERS,
TIMER_STATS and HPET (but according to /proc/timer_list, hpet is not active),
but no IRQ_BALANCE.
And for the boot options (?), /proc/cmdline is :
root=UUID=349f275c-a633-4d1d-8ab7-b3a75d67dc51 ro locale=fr_FR

lspci -vv, lspci -vn, /proc/config.gz, /proc/timer_list, lsmod,
/proc/interrupts, /proc/vmstat, ps auxf, and dmesg (with and
without the bug's logs) outputs at

Thank you.

To save somebody else from guessing, that's HIRoshima, i.e. the correct
URL is http://hiroshima.zouh.org/~ben/2.6.23-rc3_bug_details.txt

Hmpf, about a second later the original URL also started to work...
