 Hi,
 
 the "VIA quirk fix" on its own gives the familiar message in dmesg
 (unrecoverable error, controller halted), so I'm compiling a kernel which
 combines this fix with your latest busdma fix to try them both together;
 as I said in my last e-mail, I'll probably not be testing this until
 Monday night...
 
 Manuel
