Hi,

I did an upgrade yesterday, the only problem I've had is with pppoa2. I 
can see an open bug report (usb/83504) that seem to be similar to my 
problem (eg. message of form "Purging 2 threads from ugen.0", and a system 
crash when booting), but I 
don't see anyone else here with the problem. I've had to go back to my 5.4 
backup as my system is useless with pppoa2. Am I alone? The priority is

chunk of dmesg:
