ok, as expected, the wait for pause ended loop, (someone with the specs pls say max HZ 
for a) wait_interruptible(_timeout)() here.
yes, I know that case must not happen and it should bug cause 
the pci config is messed up already, but generally such loops are 
surely inacceptable in such a kernel thread.

will dump the config data to here, maybe its readable to the aic devs. 

then disable test and will let it bug somewhere further where the 
cause can possibly be easier seen.
