The list doesn't bounce URLs. Please make then clicky in future.

As it is, your kernel has oopsed in submit_bio() when writing a log
buffer writing a dummy log record.

The xfs_log_worker is trying to cover the log, and it seems like the
IO subsystem below it is doing something wrong. Perhaps Tux-on-Ice
is killing the IO subsystem without having first stopped all the
async filesystem processing first?

Looks like a Tux-on-ICE problem to me...

Cheers,

Dave.
