Using the debug option in the boot menu gives (hand transcript):
----------
Fatal trap 12: page fault while in kernel mode
fault virual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc057c368
stack pointer = 0x10:0xdc5a8b58
frame pointer = 0x10:0xdc5a8b58
code segment = base 0x0, limit 0xffffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL=0
current process = 227 (devd)
trap number = 12
panic: page fault
----------
Being a physicist, I naturally repeated the process a few times and got the following lines different:
----------
stack pointer = 0x10:0xdc5b4b58
frame pointer = 0x10:0xdc5b4b58
current process = 245 (devd)
----------
stack pointer = 0x10:0xcc50eb58
frame pointer = 0x10:0xcc50eb58
current process = 245 (devd)
----------
stack pointer = 0x10:0xdc5b4b58
frame pointer = 0x10:0xdc5b4b58
current process = 245 (devd)
----------
stack pointer = 0x10:0xdc5b4b58
frame pointer = 0x10:0xdc5b4b58
current process = 245 (devd)
----------
... don't know if that helps.
