ASoC: Intel: avs: Coredump and recovery flow
In rare occasions, under stress conditions or hardware malfunction, DSP
firmware may fail. Software is notified about such situation with
EXCEPTION_CAUGHT notification. IPC timeout is also counted as critical
device failure. More often than not, driver can recover from such
situations by performing full reset: killing and restarting ADSP.
