Since it worked before, it sounds like DMA buffer allocation issue.
Can you try attached patch? It doesn't fix your issue but it checks
return code correctly and we can know whether DMA buffer allocation
was successful or not.
If DMA buffer allocation was successful I have no idea. If you see
DMA buffer allocation failure you probably can workaround the
issue like this:
Step 1. Make static kernel with your sound drivers.
Step 2. add vm.old_contigmalloc=1 in /etc/sysctl.conf
If you needed step2, maestro3 driver needs rewriting for its memory
management code.
Cheers,
