As far as I can tell it resolves the problem. There is a remaining issue that the audio mixer needs to be setup manually since for some reason the alsastate isn't restoring a sane value (not sure why). That can be documented in the fri2 wiki though. I don't think you have to document anything for the FRI2 in the release notes. (I am having trouble with my serial console, but that may just be my hardware.... I don't see us getting to the bottom of that before release) -- Darren > > Thanks, > Nitin > > >> -----Original Message----- >> From: [email protected] [mailto:meta-intel- >> [email protected]] On Behalf Of Darren Hart >> Sent: Tuesday, April 23, 2013 2:34 PM >> To: Meta Intel >> Cc: Darren Hart >> Subject: [meta-intel] [PATCH] fri2: Disable MSI interrupts for the HDA device >> >> MSI interrupts fail when using the EFI firmware on the FRI2.
