System: MSI KT3 Ultra2 (KT333/VT8235 bridges) XP1700+ 1G DDR RAM Seagate ST380021A Plexwriter PX-W2410A Radeon 32M SDR Ensoniq 5880 AudioPCI SMC EtherPower II RedHat 8.0 GCC 3.2
Linux 2.4.20-pre10:
Setup A: IDE0 = HD, IDE1 = HD and Setup B: IDE0 = HD, IDE1 = ATAPI CD-Writer w/ide-scsi driver
Everything works, but only in PIO mode.
Linux 2.4.20-pre10-ac2:
Setup A: IDE0 = HD, IDE1 = HD
Everything works in UDMA mode 5.
Setup B: IDE0 = HD, IDE1 = ATAPI CD-Writer w/ide-scsi driver
The HD works in UDMA mode 5, but the ATAPI CD-Writer is unusable. When I try to mount a CD-ROM, the kernel spews 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=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=0x49 { DriveReady DataRequest Error } hdc: status error: error=0x04 hdc: drive not ready for command hdc: ATAPI reset complete Usually the CD-ROM can be mounted and read, although it is extremely slow. Once, however, the kernel paniced before it got as far as mounting it. Unfortunately the oops was not captured in the logs, but I think its last words were something like "AIEEE, killed interrupt handler".
If anyone is willing to look into this problem I'd be happy to send you whatever logs, config, and /proc information you need. I can also try out new patches.
