I've noticed this([   14.630815] hda_intel: azx_get_response timeout,
switching to polling mode: last cmd=0x00bf1c00
 with 2.6.26-rc2 or 3, when connecting external speakers to listen to
music(keep in mind this was only once),
Now with kernel 2.6.26-rc5 and 6 I'm seeing this pop up every so
often,(seen this three times now). attached is dmesg of the message.
If I see anything else I'll send a post.
regards;
