SCSI reset during CD write

[doug reeder]

Whenever I try to burn a CD on our HP Kayak with a Yamaha CRW4416S
drive running RH 6.1, the process goes fine until the "fixating"
stage, whereupon cdrecord reports an error involving the SCSI bus
being reset:

[root@eroica tmp]# cdrecord -v speed=1 dev=0,2,0 -data scores.iso
.
.
.
Fixating...
CDB: 5B 00 02 00 00 00 00 00 00 00
Sense Bytes: 70 00 06 00 00 00 00 0A 00 00 00 00 29 00 00 00
Sense Key: 0x6 Unit Attention, Segment 0
Sense Code: 0x29 Qual 0x00 (power on, reset, or bus device reset occurred) Fru 0x0
Sense flags: Blk 0 (not valid)
cmd finished after 23.796s timeout 480s
Fixating time: 37.668s

The disk is never mountable in any other CD drive, and usually won't mount in
the Yamaha drive. (The TOC does not appear to be valid; it typically
looks something like:

first: 0 last 1
track: 0 lba: 0 ( 0) 00:02:00 adr: 1 control: 4 mode: -1
track: 1 lba: 0 ( 0) 00:02:00 adr: 1 control: 4 mode: -1
track:lout lba: 0 ( 0) 00:00:00 adr: 1 control: 4 mode: -1

). The FIFO is never exhausted during the write process.

The SCSI card appears to be an NCR53C8xx:

[root@eroica tmp]# cat /proc/modules
.
.
.
pcnet32 9628 1 (autoclean)
ncr53c8xx 52264 6

Any suggestions?

I had the same problem some time ago in a different environment (Adaptec controller,
Windoze NT). Could solve it by configuring the adapter to something like 'allow
disconnect' for all drives (means the drives release the scsi bus while being busy
with themselves).
Hope that helps, good luck

I had the exact same problem using an ncr53c810 with the ncr53c8xx module
and a smart and friendly SCSI cdrom drive. The following url gives
available module arguments:

http://dv1.cs.kau.se/lxr/http/source/drivers/scsi/README.ncr53c8xx

When i used "sync:255" I was able to burn cds using cdrecord from the
command line but X-CDRoast and gtoaster both gave me coasters.

I've since switched back to an older ava1505a card and everything's
working great but I hope this info helps.
