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.

Greg, any udev breakage that could affect /dev/null?

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?
