=46or the sake of reliability I've put a (temporary) static copy of the=
 page here:
http://www.pateam.org/archive/tmp/serrparitylogs.html
It still links to the original URL for CSS and stuff, but at least the
logs are there.

=46WIW, the above dump is not the final message, from what can be seen
of the other dumps. As a matter of fact, it happens way before the
actual crash, which is triggered by loading drivers (SYM, afaict).
Output is garbled by GSP, and it seems to me that the dump with
pdcchassis=3D0 is truncated. Could the author post a full dump of the
boot log with pdcchassis=3D0 please? (and maybe use pastebin? ;-)
