Good point :) Okay, copied manually from the console:
end_request: I/O error, dev sda, sector 8690896
Buffer I/O error on device dm-0, logical block 1081344
JBD2: I/O error detected wen updating journal superblock for dm-0-8
end_request: I/0 error, dev sda, sector 1026056
etc
I gather device mapper and journal errors are caused by the preceding
low level error.

Yeah, was hopping to avoid the delay though. Its already sucked two
days of my time so I might just have to bite the bullet :-(
