Hi Keith,

I have been able to reproduce the bug (randomly - needing a few reboots 
to make it happen) on a 2.6.15-rc3 kernel.

System is an HP DL140G2 with following SATA controller (from lspci -vv) :

0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150 
Storage Controller (rev 02) (prog-if 8a [Master SecP PriP])
        Subsystem: Hewlett-Packard Company: Unknown device 3208
        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: 0
        Interrupt: pin A routed to IRQ 17
        Region 0: I/O ports at <unassigned>
        Region 1: I/O ports at <unassigned>
        Region 2: I/O ports at <unassigned>
        Region 3: I/O ports at <unassigned>
        Region 4: I/O ports at 1470 [size=16]
