I have lost one of my CDROM drives (HL-DT-STDVD-RAM GH22LP20/2.00) after going from 7.4 to 9.1 when using ATA_CAM. It is attached to a Promise PDC20268 UDMA100 controller. A standard harddisk drive attached to this controller works well. Cables, controller and drive where replaced already. Kernel gives me: atapci1: <Promise PDC20268 UDMA100 controller> port 0xb000-0xb007,0xa800-0xa803,0xa400-0xa407,0xa000-0xa003,0x9800-0x980f mem 0xdf800000-0xdf803fff irq 11 at device 12.0 on pci0 ata2: <ATA channel> at channel 0 on atapci1 ata3: <ATA channel> at channel 1 on atapci1 ... ada0 at ata2 bus 0 scbus2 target 0 lun 0 ada0: <Maxtor 7B300R0 BAH41G10> ATA-7 device ada0: 100.000MB/s transfers (UDMA5, PIO 8192bytes) ada0: 286188MB (586114704 512 byte sectors: 16H 63S/T 16383C) ...

Attaching the CDROM drive to the controller that is integrated on the mainboard (Intel PIIX4 UDMA33 controller) does not show this problem (but here I don't have UDMA66). It also works when not using ATA_CAM: ... acd0: DVDR <HL-DT-STDVD-RAM GH22LP20/2.00> at ata3-master UDMA66 ... So this semes to be a problem with the Promise controller and ATA_CAM. Any ideas? Or should I file PR? Thanks, -Andre
