I'm not certain how I might gather more information about this bug, but
the upgrade of 8.0 to 8.1 on a stock Dell L700cx lost the CDROM (which
obviously worked during the upgrade ;)
dmesg only reports (hdc is the cdrom)
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
end_request: I/O error, dev 16:00 (hdc), sector 64
isofs_read_super: bread failed, dev=16:00, iso_blknum=16, block=32
and then every command which tries to access the supermount cdrom
causes a panic, always at super.c line 274. Here's a typical
sequence:
