with 2.5.67-mm2, it is SA_INTERRUPT|SA_SHIRQ and looks like it can call 
multiple interrupts at once.  I am not sure what SA_SHIRQ does, but this 
does not address the case where one CPU holds an interrupt for one card 
and the other CPU holds the interrupt for the other card.

I moved the line 

rme9652_write(rme9652, RME9652_irq_clear, 0);

to after the snd_pcm_period_elapsed calls in the hopes that they would be 
run in interrupt context, but it did not make a difference.  The backtrace 
looks a little different, but it's still the same crash.
