since i activate ataidle i have this errors:
ad8: FAILURE - WRITE_DMA48 timed out LBA=314770799
+ad8: TIMEOUT - READ_DMA retrying (1 retry left) LBA=12207
+ad4: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing request directly
after disable it, this messages are gone.
so i think its a problem with ataidle, but why this panics the kernel?
