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:

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?

Magallón, does the attached patch fix the problem?

Alan, it seems that 0x848a indicates CFA device iff the ID data is from
IDENTIFY DEVICE. When the command is IDENTIFY PACKET DEVICE, 0x848a
seems to indicate a valid ATAPI device.

From ATA8-ACS, 7.17 is IDENTIFY DEVICE.

And, 7.18 is on IDENTIFY PACKET DEVICE.

So, when the output is from IDENTIFY PACKET DEVICE, 0x848a doesn't have
any special meaning. It indicates a valid write-once, removable media,
ATAPI device with 16bytes CDB.

The attached patch makes sanity checking logic in ata_dev_read_id()
check for CFA only if IDENTIFY DEVICE is used.

Thanks.

Apparently so - thats a detail I didn't know about.
