Re: PROBLEM:SCSI repeatable 2.4.22 bug

Sorry for sending previous email unfinished,
my finger was quicker than my mind...

I am trying to switch off dma on DVD-ROM which is used by ide-scsi,
hdparm is useless, should I try to hdparm it before ide-scsi driver loads or use some command under scsi?

TIA,

Flavio

Hi,

the hd and dvd light are constantly on from boot onwards (using vanilla
2.4.22 and the /var/log/messages is a sequence of messages as in
attachment).
2.4.20 vanilla has no problems whatsoever...

Your drive is returning more data than it was asked for or expected.
What model drives do you have and does turning off DMA for non disk fix
it ?

I have a fujitsu laptop with:

IC25N030ATCS04-0 ibm 30gb ide drive

ide dvd/cdrw drive using ide-scsi driver:

cat /proc/scsi/scsi:
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: TOSHIBA Model: DVD-ROM SD-R2212 Rev: 1F15
Type: CD-ROM ANSI SCSI revision: 02

hdparm is not present on disk, so I suppose hd parameters are not
changed by rc scripts...
