8.0-STABLE SMP panic on XServe G4 SMP

[Kevin Day]

8.0 seems to work fine UP on my XServe G4, but trying SMP I'm getting a panic on boot. In a UP GENERIC kernel, I'll get:

pmu0: <Apple PMU99 Controller> mem 0x16000-0x17fff irq 25 on macio0
pmu0: [ITHREAD]
iichb0: <Keywest I2C controller> mem 0x18000-0x18fff irq 26 on macio0
iichb0: [ITHREAD]
iicbus0: <OFW I2C bus> on iichb0
iicbus0: <unknown card> at addr 0x1c0
ata0: <Apple MacIO Ultra ATA Controller> mem 0x1f000-0x1ffff,0x8a00-0x8aff irq 19,11 on macio0
ata0: [ITHREAD]
ohci0: <Apple KeyLargo USB controller> mem 0x80081000-0x80081fff irq 27 at device 8.0 on pci2
ohci0: [ITHREAD]
usbus0: <Apple KeyLargo USB controller> on ohci0
ohci1: <Apple KeyLargo USB controller> mem 0x80080000-0x80080fff irq 28 at device 9.0 on pci2
ohci1: [ITHREAD]
usbus1: <Apple KeyLargo USB controller> on ohci1
pcib3: <OFW PCI-PCI bridge> at device 17.0 on pci1
pci3: <OFW PCI bus> on pcib3

But on SMP right before "usbus0" I get "panic: resource_list_alloc: resource list is busy".

Is this a known issue? If not, any guidance on what to look at first?
