2.4.18 + 19pre10 + ac2 gives cdrw ide-scsi data discarded errors

[Mark Cooke]

Hi all,

On a brand new system (Abit IT7), I've been getting errors writing CDs.
As it's a new machine, I've not successfully written any CDs yet, so it
is potentially a faulty cdrw drive, but I'm also a little suspicious that 
it's a possible issue with the motherboard.

Configuration:

Two hard disks on the highpoint 374, raid-1.
DVD on hda
CDRW on sg0/sr0 (hdc before setting up ide-scsi)

Using xcdroast, gives:

Performing OPC...
cdrecord: Input/output error. send opc: scsi sendcmd: retryable error
CDB:  54 01 00 00 00 00 00 00 00 00
status: 0x0 (GOOD STATUS)
cmd finished after 200.114s timeout 200s
cdrecord: Resource temporarily unavailable. OPC failed.

when trying to write an image.

In syslog:

lun 0 UNKNOWN(0x54) 01 00 00 00 00 00 00 00 00 

Google didn't turn up anything recent about discarded data, but I recall 
there being some recent changes to ide-scsi in 2.4.x.

Anyone else seeing this with very recent 2.4.x ?  Any thoughts about how
to proceed ?  It is difficult to try earlier kernels as the highpoint 374
is only very recently supported.

Cheers,

Mark
