SubjectRe: XFS shutting down due to IO timeout on SATA disk (pata_via for CX700)
Hello,

I try not to break lines from dmesg, lspci and and other commands'
(formatted) output as those tend to get pretty hard to read when
line-wrapped.
Sorry if I wrapped my text after 80 columns.

I checked it though there were no errors logged nor any other information
that would catch attention. The disk/machine is pretty unused (a year old
but low uptime, a few hours those days with uptime)

Anyhow smaprtctl's output is blow.
