I tried rt4-sr2 and got the same results (also with idle=poll for
completeness :). 

I'm beginning to think that it's some sort of interaction with the BIOS
(either that or just weird hardware). When I compared the two sets of
boot outputs, the boot that succeeded (dmesg-rt4-sr2.good.txt, with
WAKEUP_TIMING, LATENCY_TIMING and LATENCY_TRACE turned off) shows APIC
probes and PCI probes that don't have corresponding prints in the failed
boot (dmesg-rt4-sr2.fail.txt). 

I tried booting variously with:
	pci=routeirq
	acpi=noirq
	lapic
but saw no change in behavior.

Have you tried booting your system with a up kernel?
