FreeBSD on an Efika

[Andrew Turner]

I have been sent an Efika[1] board from Genesi.

When booting FreeBSD on it I found it would stop before the
printing copyright notice. The problem seems to be similar to
http://lists.freebsd.org/pipermail/freebsd-ppc/2006-June/001692.html (I
have had the same output before)

After some investigation I found the kernel was stopping when it
reached sys/kern/subr_msgbuf.c line 125 [2]. The msgbuf struct appears
to point to an invalid address. The address of the struct comes from
virtual_addr[3]. This indicates the virtual_addr points to an invalid
area of memory on this device.

By commenting out sys/kern/subr_prf.c line 924 [4] and using the ofw
console I managed to get past the copyright notice. It now stopped
later attempting to read from memory in the virtual_addr range.

Has any one got any suggestions how I could fix this?
