Second, I have an issue: I tried 2.6.29 but my maschine is always freezing after 2 minutes and about 10 seconds running. So I bisected that beast and found the cause (?): commit 1e91477aa335fc1c97eb15649ed1a1714cc758ec Author: Borislav Petkov Date: Tue Jan 6 17:20:57 2009 +0100 ide-cd: start DMA before sending the actual packet command as it is done for all other IDE ATAPI devices. There should be no functionality change resulting from this patch. Signed-off-by: Borislav Petkov Signed-off-by: Bartlomiej Zolnierkiewicz I tried to revert this patch in 2.6.29 but the revert produced a merge conflict and I don't have the knowledge to resolve this conflict. So as a quick workaround I disabled ide-cd in my kernel config: # CONFIG_BLK_DEV_IDECD is not set which does the trick but is of course no solution. (I'm writing this email with 2.6.29 and disabled ide-cd.) My CD is a ide dvd drive attached to an promise pci-controller: $ /usr/sbin/lspci 00:00.0 Host bridge: VIA Technologies, Inc.
