as I said in a prior message, that is very possible.
Here is the panic message I copied down by hand, followed by the
dmesg for the machine when booted with PNP OS set to 'yes'. This
panic text appears immediately after the message:
Waiting 15 seconds for SCSI devices to settle
and is preceeded by two blank lines. As you see, this is a fresh
install, I haven't even gotten around to a custom kernel yet.
Fatal trap 12: page trap while in kernel mode
fault virtual address = 0x1c
fault code = supervisor read, page not present
IP = 0x8:0xc011e685
... <rest of the registers>
processor flags = interrupt enabled, resume,
IOPL=0
current process = idle
interrupt mask =
trap number = 12
panic: page fault
Syncing disks ... done
Automatic <rest of the stuff>
This is the dmesg when booted with PNP OS set to yes:
