tezava s cd-rw IDE-SCSI emulacija

[Mario]

Hi,


V racunalniku imam sledece device

hda: Maxtor 6E040L0, ATA DISK drive
hdb: HL-DT-ST GCE-8320B, ATAPI CD/DVD-ROM drive
hdf: WDC WD400BB-00CAA0, ATA DISK drive
hdg: WDC WD800AB-00CBA1, ATA DISK drive


Pri bootanju mi javlja error za CD-RW :

hdb: attached ide-scsi driver.
hdb: irq timeout: status=0xd0 { Busy }
hdb: DMA disabled
hdb: ATAPI reset complete
hdb: irq timeout: status=0xc0 { Busy }

ide-scsi: hdb: unsupported command in request queue (0)
end_request: I/O error, dev 03:40 (hdb), sector 4
ide-scsi: hdb: unsupported command in request queue (0)



Imam vcitane module

"sg" and "ide-scsi"



v /etc/lilo.conf

imam dodano

append="hdb=ide-scsi"


Tezava je v tem, da ko imam v lilo.conf dodan zgoraj naveden parameter "append=...."
potem mi CD-RW ne zaznajo programi x--cdroast, k3b...

Ce pa tega parametra nimam v lilo.conf, pa mi CD-RW pogon normalno zazna, ampak mi potem zapisovanje na CD zelo pocasno, buffer na 10% - 20%...


DMA imam vkljucen za vse device.

/dev/hdb:
 setting 32-bit IO_support flag to 1
 setting unmaskirq to 1 (on)
 setting using_dma to 1 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)



Ima kdo kako idejo, kako bi resil ta problem?
