Got a weird error message (kernel dmesg output below). Is it likely
this type of error could be caused by a loose cable or connector?
Or is there something else at play here?
The card is a "Adaptec AHA-2940U2/U2W / 7890/7891" (talking to
the 1 SCSI disk, sda).
Earlier today, one of the scsi-based partitions went "offline" (these
things seem to come in spurts)...
Thanks,
Linda
