Well, the list of loaded modules is in the report below; anyway I've noticed
that a similar oop (or BUG) happens often at boot, maybe it can be related to
log replay. On this machine I change quite often kernel (at least, at every
MM release) and I've noticed that reboot is very "dangerous" moment for my
jfs volumes. Say, several reboots with rc4-mm1, no problems. Complied
rc4-mm2, booted with BUG. rebooted back with rc4-mm1, BUG. it has no pattern
that I can find, but it seems related to some strange state of written data
that confuses jfs code.
Last time, something happened not during boot but where unmerging after glibc
merging (so after heavy HD load): unmerge got stuck executing rm (D state)
and after reboot all files related to glibc were corrupted or damaged (even
lib*so symlinks), maybe jfs was hit hard and was unable to wrote down data in
a right way.
This happens with mm series kernel, I've no data for vanilla kernel.
today I've find the following BUG on logs of the same machine, but the system
is still up & running (more or less :) ), so if needed it's possible to
collect more data.
