Comment 55 for bug 116996

Don't know if this will help this bug or not but I am a ubuntuforums member and have been trying to keep spirits high and try to console those who feel that Ubuntu has really screwed up here, sad to say that I don't have much of an arguement when something as large as this occurs.

Anway, back to the subject at hand, all my SATA drives are still being handled by SCSI emulation (i think that's what it means when you see SATA devices show up with the /dev/sdXY device id) Here is my output from lspci -vvv for my IDE controllers.
00:0f.0 IDE interface: VIA Technologies, Inc. VT8237A SATA 2-Port Controller (rev 80) (prog-if 8f [Master SecP SecO PriP PriO])
        Subsystem: ASRock Incorporation Unknown device 0591
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
        Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 32
        Interrupt: pin B routed to IRQ 21
00:0f.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 07) (prog-if 8a [Master SecP PriP])
        Subsystem: ASRock Incorporation K7VT2/K7VT6 motherboard
        Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
        Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 32
(NOTE: I am not sure why the second IDE controller doesn't have a line for the Interupt but it doesn't)

This is a ASRock 775dual-VSTA motherboard. And this is what shows for libata under lsmod:
libata 125720 2 sata_via,ata_generic

So this chipset does NOT have this problem, I hope this info is helpful.
