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?
