There is a bug in timeout handling (easiely fixed by increasing the timeouts),
which produces this error when your drive has read-errors and retrys or
repairing the data (using the ECC code on the disk) takes too long.
I had the same problems with a sequest-drive and a bad media.
I don't know if the timeot handling is fixed in newer releases.
If I remember correct, the unexpected reconnect from the drive after the timeout
kills the system.

I would start worrying about the data on the disk if I were you ...
