Yeah, not a whole lot to go on is there ;-)

Converting the PC (c02c1544) to a code line with gdb or addr2line would
be a good start I think.

You could also consider hacking up an earlyprintk via Xen by dropping a
xen_raw_console_write into vprintk_emit once the buffer is formatted and
see if that gets you any useful console output.

(Somebody really needs to make a patch for proper Xen capable
earlyprintk for arm...)

Ian.
