I have started to see a lot of I/O errors on my system since I started to
test suspend. (see below).
Do these indicate hardware problems or software ? I have also included a
snip of dmesg where the suspend /wake messages show up. Only problem I see
is in an acpi event which is not handled. I/O errors seem to occur only
during startup.
If these are hardware errors are there any Linux OSS utilities to mark bad
sectors on mounted volumes or do a non-destructive surface scan ?
sample I/O errors: (note: hdc is my lvm partition, hda is windows fat32, hdb
is /boot)
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x51 { IllegalLengthIndication
LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 0
