I guess I spoke too soon earlier: the i386 kernel I built from a sup
of about 4 hours ago paniced on boot with:

uvm_fault(0xf625f000, 0x1625d000, 0, 1) -> 1
kernel: page fault trap, code=0
stopped in swapper at   _execsigs+0x7c: testl  %edx,0(%ecx,%edi,1)
db> trace
_execsigs(f625d000,f625d000,efbfdfec,efbfdff5,f011a13f) at _execsigs+0x7c
_sys_execve(f625d000,f625cf88,f625cf78,efbfdfec,efbfdff5) at _sys_execve+0x4b4
_start_init(f625d000) at _start_init+0x15f
bad frame pointer: 0xf021cf08
db> examine 0xf021cf08
0xf021cf08:     7fffffff


Any ideas?

Cheers,

Patrick
