I have a directory on my local filesystem that I cannot access on
2.4.0-test10. It happens when I try to "ls" in this bad directory, and ls
segfaults.
I can poke around tomorrow morning without a reboot, but then I'll have to
reboot (so please respond via email if I can do anything). I tried
grinding the message through ksymoops-2.3.5, and it complains with this
error:
Warning (Oops_code): trailing garbage ignored on Code: line
Text: 'Code: Bad EIP value. '
Garbage: 'IP value. '
Using defaults from ksymoops -t elf32-i386 -a i386

Error (Oops_code_values): invalid value 0xE in Code line, must be 2, 4, 8 or 16

Here's the oops from /var/log/messages:

Are you sure that is ksymoops 2.3.5? My version of 2.3.5 handles
'Code: Bad EIP value. '. ksymoops >= 2.3.4 should handle it correctly.

sys_lstat64+55 has branched to the value in eax and blown up. It looks like
the data in eax is a kernel address shifted right one byte.

Many apologies, it's late and I ran the default ksymoops (0.7c) instead of
./ksymoops
However, after running the real ksymoops against it, it gives nothing
new; I suppose since 'ls' is dying and the stack is from 'ls', that's why.
Is there anything else I should do before booting back to a 2.2.17 kernel?
As proof that I ran the right ksymoops this time:
ksymoops 2.3.5 on i686 2.4.0-test10. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.0-test10/ (default)
-m /boot/System.map-2.4.0-test10 (specified)
