Hello,

* In the patch, you need to update pdev->class too after updating the actual register.
In theory the class code should be derived from the PCI device itself though, and in theory it's already set to 0x1018a (docs say the two bits for the mode always read 0 so the real PCI class code in native mode is always going to be 0x1018a even if it's meant to be 0x1018f) and in the device tree, 0x1018f.

Patch updated. I think that may have been the bug.

* Dunno about the specific chipset but via PATAs usually work fine in native mode.
Usually.. but this is a VIA chipset.

The irq 0 fix came in between 2.6.22-rc7 and 2.6.22?

Heh.. yeah, via is well, via. And the fix was after -rc7, IIRC.

OK, applied latest fix (With class code update) and it seems the timeouts are still there. HD seems to works fine, but no DVD drive after boot. I attached dmesg and
lspci to bugzilla report.

In case if this is device related I currently using Pioneer DVR-111

* In the error message, ata2.00 timesout requests to configure udma/33 but gets successfully configured for udma/25. I wonder it's drive-specific problem. Can you put another device at the secondary channel and test?
I did another change: exchanged the cables on the mother board, so CD is hda, and HDDs are hdc and hdd. And what a wonder: CD is now detected correctly, while HDDs, which are now on the secondary IDE as slave and master, don't.

Hmmmm... Thanks. That tells us that IRQ delivery still doesn't work. Maybe it needs two IRQs.
