I have to admit, I saw the oops only with a glimpse of the eye, trying to do
other tasks at that moment about a week ago. The oops also left no trace in
the syslog. As syslog is on a reiserfs partition, perhaps reiserfs refused
no write anything after the oops. Trying to reproduce by mounting the bogus
sda4 partition of the usb stick on two different setups, now reiserfs
clearly refuses to mount it. Perhaps the oops was unrelated. 

Find appended an oops happening yesterday, related to reiserfs too. Probably
totally useless, as run on a custom Suse kernel. A reiserfsck after the oops
corrected some errors, perhaps introduced by the oops one week earlier. I
don't understand what to do about the missing ksyms..

B.t.w.: While I have you attention, can I point you to 
http://www.ussg.iu.edu/hypermail/linux/kernel/0410.1/1246.html
where I reported a Linux missbehaviour and a possible patch. I tried to get
the attention of several kernel developpers, to no avail so long ...

Cheers

=== ksymoops decoded ===
ksymoops 2.4.9 on i686 2.6.11-rc4-bk2.  Options used
     -V (default)
     -k /proc/kallsyms (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Warning (read_ksyms): no kernel symbols in ksyms, is /proc/kallsyms a valid ksyms file?
No modules in ksyms, skipping objects
No ksyms, skipping lsmod

is unreliable, take these instructions with a pinch of salt.
