Hello!
The problem described at https://bugzilla.redhat.com/show_bug.cgi?id=351451 and
at http://ubuntuforums.org/showthread.php?t=655772 and supposedly fixed by the
patch http://kerneltrap.org/mailarchive/linux-kernel/2007/11/25/445094 is still
there. I have compiled 2.6.24-rc7 kernel and booted my PC with it just to find
out that my SATA DVD-RW is
There's this patch which was intended to fix it:
http://lkml.org/lkml/2007/11/22/148
which hasn't been merged yet. I see now that there was some further
discussion from someone saying that didn't fix the problem for them,
which I wasn't CCed on.. It looks like in their case, libata is
receiving SGs with DMA addresses above 4GB even though the block layer
bounce limit is set to 32-bit. That's the mechanism that sata_nv depends
on to ensure that it gets proper addresses when accessing ATAPI devices
where it is limited to 32-bit DMA.. Could that be breaking or
insufficient somehow?
