Not to "toss this one back" or anything like that, but those syslog oopses 
show a lot of errors and only a few involve pvrusb2.  And of those that 
involve pvrusb2, it appears that every case is happening in code called by 
pvrusb2, not pvrusb2 itself.  I did look to see if anything "jumped out" 
to suggest a pvrusb2 problem but I didn't see anything of that nature. 
Right now I'd say that pvrusb2 is an innocent bystander in a larger 
problem :-(

Any chance you can attach a separate USB controller to your system and 
test with that?
