Err, my burner got lost this summer ;).
This is really not a bug of _this_ kernel, because I noticed it dissapeared
with the previous release also, just before going on vacation... But as it
did not come back with this relase, I report it here.
Last kernel that I have tried that worked was 2.6.18-rc2-mm1. With this
relase, it is gone still. dmesg for both kernels is below.
The only thing I hace noticed is the different IRQ assignment between
them.
Any ideas ? TIA.
dmesg for rc2-mm1:
scsi0 : ata_piix
ata1.00: ATAPI, max UDMA/33
ata1.01: ATAPI, max MWDMA0, CDB intr
ata1.00: configured for UDMA/33
ata1.01: configured for PIO3
Vendor: HL-DT-ST Model: DVDRAM GSA-4120B Rev: A111
Type: CD-ROM ANSI SCSI revision: 05
Vendor: IOMEGA Model: ZIP 250 Rev: 51.G
Type: Direct-Access ANSI SCSI revision: 05
dmesg for rc5-mm1:
ata1.00: failed to IDENTIFY (device reports illegal type, err_mask=0x0)
Hmmm... Strange.
The related code hasn't changed much between rc2-mm1 and rc5-mm1. We're
talking about 2.6.18-rc2-mm1 and 2.6.18-rc5-mm1, right?
Can you try the attached patch and report what the kernel says?
