This machine has a known good Samsung SATA DVD on ICH8 [8086:2820]. With kernel 2.6.23-rc1 I now get the following: >ata_piix 0000:00:1f.2: version 2.11 >ata_piix 0000:00:1f.2: MAP [ P0 P2 P1 P3 ] >ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 19 (level, low) -> IRQ 19 >PCI: Setting latency timer of device 0000:00:1f.2 to 64 >scsi2 : ata_piix >scsi3 : ata_piix >ata3: SATA max UDMA/133 cmd 0x0001ec00 ctl 0x0001e882 bmdma 0x0001e400 irq 19 >ata4: SATA max UDMA/133 cmd 0x0001e800 ctl 0x0001e482 bmdma 0x0001e408 irq 19 >ata4.00: ATAPI: TSSTcorpCD/DVDW SH-S183A, SB00, max UDMA/33 >ata4.00: applying bridge limits >ata4.00: configured for UDMA/33 >ata4: EH pending after completion, repeating EH (cnt=4) >scsi 3:0:0:0: CD-ROM TSSTcorp CD/DVDW SH-S183A SB00 PQ: 0 ANSI: 5 The "EH pending after completion" is new and did not occur with 2.6.22. Apart from that message, things seem fine. /Mikael - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
