Hello,
got a series of oops (see below) while stress-testing my machine:
Linux 2.4.2, Epox-EP8KTA2 Athlon 1GHZ, 512 MBram, IBM-30GB-IDE-drives, latest debian-woody
the machine was copying files between two ide-drives, compiling two software packages,
and stuff like "find /" was running. Machine was not using much swap.
All of them seemed to relate to kmem_cache_free, excerpts from trace follow,
and after that you find the disassembled kmem_cache_free-function.
PLEASE EMAIL me DIRECTLY as i am not following the kernel list actively.
Hope it Helps (contact me for further infos),
Holger
