Hi,

Sometimes (1 in 5 boots) I see the following: azx_get_response timeout, switching to polling mode: last cmd=0x014f0900

I initially blamed MSI that I enabled explicitly. If it is enabled, there is another timeout just before this line. Now I explicitly disable msi, and still see this.

It seems that codec hangs or so.

Unless it switches to the single_cmd mode, this isn't so serious at all. Usually this is a problem of either the timing or that the IRQ isn't generated by the chip properly. But the communication via CORB/RIRB still works usually, so the driver runs fine in the polling mode.

thanks,
