So I did that and I can confirm that I no longer got OOPS but those DMA turn offs were back instead as they used to happen with <= 2.6.28 kernels: [ 663.442788] hdd: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } [ 663.445040] hdd: cdrom_decode_status: error=0x40 <3>{ LastFailedSense=0x04 } [ 663.446768] ide: failed opcode was: unknown [ 663.454549] hdd: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } [ 663.456681] hdd: cdrom_decode_status: error=0x40 <3>{ LastFailedSense=0x04 } [ 663.458541] ide: failed opcode was: unknown [ 663.464783] hdd: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } [ 663.466847] hdd: cdrom_decode_status: error=0x40 <3>{ LastFailedSense=0x04 } [ 663.468764] ide: failed opcode was: unknown [ 663.473414] hdd: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } [ 663.475365] hdd: cdrom_decode_status: error=0x40 <3>{ LastFailedSense=0x04 } [ 663.477259] ide: failed opcode was: unknown [ 663.477406] hdd: DMA disabled [ 663.520043] hdd: ATAPI reset complete So yes, I can confirm that the patch fixes the OOPS with 2.6.30-rc5 and 2.6.30-rc6-git5. I'm looking forward to seeing the patch included in 2.6.30-rc7 and 2.6.29.x, it looks pretty important to me. What is more, I "played" a bit with IDE cabling and switched my CD/DVD drive to IDE master and I could not even reproduce the errors above (and hence annoying DMA turn off is gone too) any more. So it is good news on all fronts for me. I leave it for you to close the bug but it is fully RESOLVED as far as I'm concerned. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
