I think I've hit something similar yesterday, with 2.6.17.1...

It's happened just after I've hit "Enter" to log in with KDM (--> KDE),
other services were starting in background (network, spamassassin) -->
high disk load.

I don't remember the exact messages but I'm pretty sure that every disk
access failed.

After a brutal reboot (Alt + SysRq + B) I've got these problems very
early (when ext3 was trying (and failing) to replay journal).

I was already thinking about an hardware failure, then I've tried
powering off/on and voilą... everything worked again.


I don't know much more because it's happened just once, and maybe it was
just a temporary hardware failure.

Anyway...
