I am sorry to report that this did not change anything - I still get the same timeouts on system boot during CD-ROM detection. To remind: 00:07.0 ISA bridge: ALi Corporation M1533/M1535 PCI to ISA Bridge [Aladdin IV/V/V+] scsi 0:0:0:0: Direct-Access ATA IC25N020ATDA04-0 DA3O PQ: 0 ANSI: 5 scsi 1:0:0:0: CD-ROM TOSHIBA DVD-ROM SD-C2502 1313 PQ: 0 ANSI: 5 BTW should not libata fail back to PIO if all DMA fails? It never does for me; this is strange. I am tempted to test ACPI driver if you have patch suitable for mainstream (not -mm) thank you -andrey - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
