Hi!
My USB CD-ROM drive (that is detected as a SCSI drive) is not being
detected on the -mm series of the Kernel.
s/USB/SATA/, I presume.
[--snip--]
-ata2.00: ATAPI, max UDMA/33
-ata2.00: configured for UDMA/33
- Vendor: HL-DT-ST Model: CDRW/DVD GCC4244 Rev: B101
- Type: CD-ROM ANSI SCSI revision: 05
Argh... yet another PCS problem. With whole -mm applied, does adding
kernel parameter 'ata_piix.force_pcs=1' make any difference?
Please provide the following info.
* the result of 'lspci -nvvv'
* dmesg output with the attached patch applied (on top of -mm).
Thanks.
