I have a BAD SCSI cdrom (3X nec - but damaged in various moves & living conditions)
... Sometimes it can't seek a track (when playing a CD) and then the SCSI system starts freezing... ... even worse is when I have to turn off the device to quit it seeking back and forth and Linux crashes:
first the cdrom crash: scsi : aborting command due to timeout : pid 68199, scsi0, channel 0, id 0, lun 0 Write (6) 03 80 0e 02 00 scsi : aborting command due to timeout : pid 68207, scsi0, channel 0, id 3, lun 0 Start/Stop Unit 00 00 00 02 00 scsi : aborting command due to timeout : pid 68207, scsi0, channel 0, id 3, lun 0 Start/Stop Unit 00 00 00 02 00 SCSI host 0 abort (pid 68207) timed out - resetting
then the system crashes [spewing these] SCSI bus is being reset for host 0 channel 0. Sent BUS DEVICE RESET to target 3 Sending DID_RESET for target 3 last message repeated 9 times
Is there any way to recover from this? The SCSI bus isn't actually _CRASHED_ (as the system still works at this point - just VERY slow).... [on a bad disk the host adapter HAS been known to crash taking the entire system with it - I have a bad SCSI disk I couldn't afford to lose for many years] - THAT is not recoverable. THIS is!
Incidentally: SCSI host adapter : Adaptec 1542B (formerly 1540A) CDrom : NEC 3x external
(I have an old 2X scsi cdrom as well to handle data CDs :) [incidentally - the drive still plays audio cd's but it can't handle data cds anymore if that matters]
I do _NOT_ know SCSI well enough to solve this myself...
TIA and G'day, eh? - Teunis
