The answer is...the USB code.
[ Nick and Joe CCed ]
If I comment out the following lines in my standard config for this
machine, SMP works:
# USB support
device uhci # UHCI PCI->USB interface
device ohci # OHCI PCI->USB interface
device usb # USB Bus (required)
#device udbp # USB Double Bulk Pipe devices
device ugen # Generic
device uhid # "Human Interface Devices"
device ukbd # Keyboard
device ulpt # Printer
device umass # Disks/Mass storage - Requires scbus and da
device ums # Mouse
device urio # Diamond Rio 500 MP3 player
device uscanner # Scanners
# USB Ethernet, requires mii
device aue # ADMtek USB ethernet
device cue # CATC USB ethernet
device kue # Kawasaki LSI USB ethernet
The USB module is still loaded when usbd cranks up, but it doesn't hang the
machine when it is loaded as a module.
I've tried two kernels, with the only difference being whether the usb code
(as listed above) is enabled or not. The kernel with the USB stuff hangs.
I've attached dmesg output from the working boot.
