Great, many thanks. That will help. Can you try now to put drivers/video/radeonfb.c from -ben8 into -ben9 (and then -ben10 if it works) and tell me if that helps ? > I can crash ben9 almost reproductibly and xmon is triggered if that can > help you (I didn't understand how to use the System.map with xmon to > decipher the stack trace, but I might send xmon output and my > System.map). > Note this might not be the same crash as ben10, because xmon is not > fired with this kernel, although it seems to crash at the early > beginning of rc.sysinit (I'm almost sure this is something about the > fonts). The system.map thing might not help (if the crash is random), but basically, you just need to copy System.map next to vmlinux (in /boot typically) and edit yaboot.conf to add a line sysmap=/boot/System.map after the image=... line (and re-run ybin to install the new yaboot.conf) With this, xmon will know about symbols. Then, you can use the "t" command in xmon to get a backtrace. Ben. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
