Any attempt to access the CD burner produces lots of messages like these: hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest } hdc: drive not ready for command hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest } hdc: drive not ready for command hdc: status error: status=0x59 { DriveReady SeekComplete DataRequest Error } hdc: status error: error=0x54 hdc: drive not ready for command The problem seems to be largely independent of the kernel version. I have tried 2.4.19, 2.4.20-preXX, and 2.5.46, with the same results. Simply turning off DMA for the CD burner does not make it work: the problem persists as long as the patch is present. On the other hand, a different CD burner (Sony CRX-140E) works just fine with the same mainboard, with the patch present. Thor
