This is resolved by turning on CONFIG_DMAR_GFX_WA.

OK, I have removed it from the list.


Thanks,

because it's default-enabled, and someone would have to consciously

disable it to intentionally trigger DMA bugs in drivers, right?

Yes.  Plus there's a statement at

http://bugzilla.kernel.org/show_bug.cgi?id=9618#c2

that clarifies it further.

That strace shows that trying to open /dev/null fails with ENXIO:


	[pid  6050] open("/dev/null", O_RDONLY <unfinished ...>

	[pid  6050] <... open resumed> )        = -1 ENXIO (No such device or address)


and everything goes downhill from there.


It would be worth looking at your /dev/null to see what kind of (broken)

device node it is, and get a clue about *why* it is broken.


Hmm. I assume the "-git6" and "-git7" are 2.6.24-rc4-gitX, ie commits


 - 2.6.24-rc5-git6: 3e3b3916a9c5c28a16528585478de19fea59816b

 - 2.6.24-rc5-git7: fbdcf18df73758b2e187ab94678b30cd5f6ff9f9


and doing a


	gitk 3e3b3916a9..fbdcf18df7


does show a SCSI merge, and two commits that touch drivers/scsi/initio.*.


James, Alan and Boaz, ideas?

Initio has been suspected broken even after all the bug fixes (I

actually said that in the last pull request).  We just couldn't get a

tester to confirm the suspicion.  The commits were for known issues but

it proved impossible to get any of the reporters to verify.


Could you direct this poster to linux-scsi and we'll see if we can

finger the root cause (which will be difficult to do without getting a

boot trace).
