My system doesnt seem to boot on alternate boots. (ie. when I
'shutdown' the system and then restart from amigados or when I
cat a kernel to /dev/reload). It always comes up with MMU faults.
I havent done a trace for when booting from amigados but I did
a trace for when booting through /dev/reload. I did two traces
and it seems to be dieing the same way each time. The process
states and stack backtrace are shown below. This happens with
both fridays -current kernel and the 1.0_Beta release kernel
(with no mods).
My system is an A2000 with an old GVP 030/23mhz accelarator + scsi
and a GVP series II scsi+ram board (the second board is my
scsi bus and I swap the first two configured devices in loadbsd
before starting up bsd). BSD is using 5 megs of 32 bit ram on
the accelerator board.
