Sorry but I interpreted your mail in this tread as that your case is driver
not loading (i.e. oopsing) *NOW* - and seems like you have this problem solved.

Regarding lockups, I had them previously on SMP machine with au8820 card but
it was quite some time ago and now I have single processor - too many changes
to tell why I do not get lockups with au8820 now.
