[Oops] i386 mm/slab.c (cache_flusharray)

[pinotj]

Here is an Oops from the kernel 2.6.0-test9 + cset-20031115_0206.txt.gz (means all current patches till 03/11/14 [PATCH] PPC32: cancel syscall restart on signal delivery ).

Seems to come from the cache_flusharray function of mm/slab.c
It occurs in general during heavy load (compilation of kernel or xfree86...), is quite reproductible but not automatic.
Same Oops on different distro/gcc (slack 9.1 et lfs 5.0).
Arch is i386 (AMD athlon-tbird 1.2GHz)

I never had this problem with 2.6.0-test8 and before.

This oops is very annoying, I got it around 5 times a day. I'm sorry but I don't have the skill to patch this. If someone can help :-) Please CC me in answer, I'm not on the lkml.

Regards,

Jerome Pinot
