Yes it works :-/

I've put some things which on the web which might be helpful:

dmesg		http://files.rfc2324.org/mptsas_panic/2.6.22-dmesg
lspci -v	http://files.rfc2324.org/mptsas_panic/2.6.22-lspci-v
.config		http://files.rfc2324.org/mptsas_panic/2.6.22-config

I'll search for the last working kernel and try to break it down to a
commit tommorow when I can get a serial console or direct access.
The Java driven console redirection is everything else than fulfilling :-(

Stay tuned.
