Kernel Bug Tracker – Bug 5789
ATAPI isn't working on sata-via
Last modified: 2007-06-18 08:09:27 UTC
According to the status report , ATAPI should work on every device that
supports it as of 2.6.15. I get some nasty bits in dmesg and it does not work.
I've got a Plextor PX-716SA and am using sata_via.
Will attach a dmesg.

This was previously being worked on at the Ubuntu bugzilla:
Probably best if you try a stock 2.6.15-rc7 kernel if possible. I'm sure Jeff
wants to make sure that nothing in the Ubuntu kernel is causing this (although
we are pretty much stock in the libata code department, it always helps).
I've built my own 2.6.15-rc7 kernel and can confirm that the issue persists, in
the same manner.
Hi, I updated to 2.6.16-rc1-mm3 and the device appears to be working. I seem to
be getting some bad burns and google tells me that I may want to disable DMA for
the drive. How do I do this without hacking at the kernel source?
