I've seen this one happen nearly every boot since then including bootups that 
are otherwise OK (no oopses), so it's probably worth more looking into rather 
than being written off as a 'once off':

uhci_hcd 0000:00:1d.3: Unlink after no-IRQ?  Controller is probably using the 
wrong IRQ.

Details:

dmesg-

ACPI: PCI Interrupt 0000:00:1d.3[D] -> GSI 16 (level, low) -> IRQ 169
PCI: Setting latency timer of device 0000:00:1d.3 to 64
uhci_hcd 0000:00:1d.3: UHCI Host Controller
uhci_hcd 0000:00:1d.3: new USB bus registered, assigned bus number 5
uhci_hcd 0000:00:1d.3: irq 169, io base 0x0000d800


lspci -vv

00:1d.3 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) 
USB UHCI #4 (rev 03) (prog-if 00 [UHCI])
         Subsystem: Intel Corporation Unknown device 4356
         Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- 
Stepping- SERR- FastB2B-
         Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- 
<TAbort- <MAbort- >SERR- <PERR-
         Latency: 0
         Interrupt: pin D routed to IRQ 169
         Region 4: I/O ports at d800 [size=32]


It's a new regression to -mm3.

For the ACPI people - I can't test with ACPI off because the machine won't boot 
without ACPI :(  [see 
http://www.ussg.iu.edu/hypermail/linux/kernel/0601.1/0044.html for what happens 
with acpi=off].
I'm not even sure if inability to boot with acpi=off is a bug or not - would 
appreciate if someone can let me know.
