Hi,
I was running something on my Dell dual p3 box (optiplex gx300). my kernel
is linux-2.4.3-ac14. I got the following message:
__rwsem_do_wake(): wait_list unexpectedly empty
[4191] c5966f60 = { 00000001 })
kenel BUG at rwsem.c:99!
invalid operand: 0000
CPU: 1
EIP: 0010:[<c0236b99>]
EFLAGS: 00010282
kenel BUG at /usr/src/2.4.3-ac14/include/asm/spinlock.h:104!
I upgrade the kernel to 2.4.5, no such problem any more.
Any idea?
Alex

I suspect something else corrupted the rw-semaphore structure, but that's very
hard to prove unless you catch it in the act. If it happens again with any
frequency, you might want to try turning on rwsem debugging.

David,
Actually it happened only once. then I upgrade my kernel to 2.4.5. problem
disappeared. I just hope this maybe a known problem.
Thanks.
