dom0/domU boot fail, trap page fault in uvm_fault()


Today, after cvs up (4.99.60 => 4.99.62), a fresh kernel rebuild for a XEN3_DOM0 or XEN3_DOMU kernel fails to boot:

uvm_fault(0xc0a09780, 0, 1) -> 0xe
kernel: supervisor trap page fault, code=0
Stopped in pid 0.2 (system) at 0: invalid address

It triggers during autoconf. domU fails right from the start (just after console), while dom0 fails somewhere after uhub* attach to usb bus.

I rebuild the same kernels after un complete cvs checkout: it faults the same way.

Anyone having the same issue?
