Hang on x86-64, 2.6.9-rc3-bk4

A reproducible, hard hang on x86-64, during bootup's fsck ("touch
/forcefsck"). Athlon64, VIA motherboard, Promise SATA, VIA SATA, 512MB,
r8169. Hang begins in 2.6.9-rc3-bk4, everything works in 2.6.9-rc3-bk3.
Hang persists in 2.6.9-rc4 and 2.6.9-final.
Symptoms: touch /forcefsck and reboot. fsck will successfully check
all partitions of the WD drive attached to Promise, then fail precisely
54% through the fsck on the Maxtor drive attached to VIA SATA. SysRq
will print out the command header, but no output, for sysrq-[tps].
sysrq-m works... for a little while. then the machine completely
hangs, no sysrq or anything.
This is 100% reproducible.
There are -no- SATA driver changes between -bk3 and -bk4 AFAICS, which
leads me to guess at VM, or x86-64 platform?
The diff between -bk3 and -bk4 is pretty small, if you ignore the ARM
and m32r arch changes.
