Hello again, guys.
Well, I just added memcpy'ing cdb to ACMD area with this patch and
thought it should work, but it didn't. Well, it kind of worked but
not really.
With this patch applied, inquiry succeeds and the device is
identified and attached with no problem. Things start to go weird
with the first TURs (test unit ready) during initialization.
When attached to sil, with the same drive and cd inside it, the first
TUR succeeds and initialization just goes on. But when attached to
ahci, it fails all five attempts of TURs with NOT READY, IN PROCESS OF
BECOMING READY (asc 0x04, ascq 0x01). This is maybe due to how BIOS
initializes ATAPI devices during POST. After five attempts, sr seems
to give up and just attaches the drive.
After boot process is completed, when a read command is issued to
the drive, the drive works fine on sil, but on ahci, the following
things happen.
* First TUR is failed with MEDIUM CHANGE (asc 0x28 ascq 0x00), which
seems reasonable.
* Second TUR succeeds.
* sr for some reason sends another TUR. This TUR gets stuck and
times out.
* Recovery kicks in and resets the device.
* sr gives up, unlocks the drive, which the drive fails with RESET
occurred.
* read fails.
The thing is that after a TUR succeeds, the drive completely locks
up. If I skip the second TUR, whtatever commands come next gets
stuck. If I don't reset after timeout, all following commands are
timed out.
When the same controller is put in legacy mode such that it's
attached to ata_piix. The drive works fine just as with sil
controller. Any ideas?
Log follows. Log is generated with #11 debug patch applied. The
first part is with sil and the second with ahci.
