Hi,
here a short oops while trying to run "find" in a glibc 2.2 root
on a Indigo2 with a current cvs 2.4.0 kernel.

Unable to handle kernel paging request at virtual address 00000000, epc == 
00000000, ra == 00000000
Oops in fault.c:do_page_fault, line 172:

       00000001 ...
Call Trace: [<88028344>] [<8800fa88>]
Code: (Bad address in epc)

I cant identify which system.map ist the correct one - -ETOMANYKERNEL
i extracted this from /proc/ksyms

8800ecb8 __rwsem_wake
8801122c do_gettimeofday

88027394 del_timer
8802869c flush_signals

This oops is reproduceable but not really nice as the fsck takes
~30 minutes :)

I'll build a fresh kernel and retry ...

Flo

     Why is it called "common sense" when nobody seems to have any?
