Is seems unreasonably hard (to me) to work out what low-level driver is
in use when we see bug reports like this.

Trolling your dmesg
(http://web.hexapodia.org/~adi/sysinfo/1240274989_cvpe4300_2.6.30-rc2-00446-ga939b96/dmesg.out)
I see 

[    2.184016] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[    2.198709] ata2.00: ATAPI: TSSTcorp DVD+/-RW TS-U633A, D200, max UDMA/100, ATAPI AN
[    2.198774] ata2.00: applying bridge limits
[    2.214107] ata2.00: configured for UDMA/100
[    2.230305] scsi 1:0:0:0: CD-ROM            TSSTcorp DVD+-RW TS-U633A D200 PQ: 0 ANSI: 5
[    2.548015] ata5: SATA link down (SStatus 0 SControl 300)
[    2.884014] ata6: SATA link down (SStatus 0 SControl 300)

so I guess that it's serial ATA, at least.

But which lower-level ata driver is being used under that?

[    0.717960] ahci 0000:00:1f.2: version 3.0
[    0.717968] ahci 0000:00:1f.2: PCI INT D -> GSI 19 (level, low) -> IRQ 19
[    0.718057] ahci 0000:00:1f.2: irq 27 for MSI/MSI-X
[    0.718097] ahci: SSS flag set, parallel bus scan disabled
[    0.718176] ahci 0000:00:1f.2: AHCI 0001.0200 32 slots 4 ports 3 Gbps 0x33 impl RAID mode
[    0.718236] ahci 0000:00:1f.2: flags: 64bit ncq sntf stag pm led clo pmp pio slum part ems 
[    0.718298] ahci 0000:00:1f.2: setting latency timer to 64

ahci, I guess.


Probably this is all perfectly obvious to the initiated, but for those
whose life revolves around telling the initiated about their bugs, this
is all unreasonably hard :(

Oh well, let's tentatively assume that we have a post-2.6.29 regression
in the libata ahci driver.
