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? -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/ | ||||||||||
