OK, very bizarre. Another instance of this pattern:

1. Recent Core Duo Thinkpad (X60, T60, X60s)
2. tainting wireless driver loaded (ipw3945, madwifi)
3. fault at "Genu" somewhere in filesystem code
4. not long after a resume from ram (?)

Not exactly the same backtrace as before
(https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=208488
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=207658), but pretty
close.

The only things I can think of are:

1. ipw3945 and madwifi are sharing some 802.11 code, which splats
this pattern into memory for some reason
2. some firmware/smm bug which end up corrupting a register (?)
3. erm? anyone?
