Hello,

can someone please run 'sudo dmesg' from a terminal window - this will open your last boot log.

I am trying to determine why my MBA takes so long to get past it's initial power on sequence - in the log I have this a few lines down about no matching GPU's:

IGPU: family specific matching fails
Matching service count = 1
Matching service count = 2
Matching service count = 2
Matching service count = 2
Matching service count = 2
Matching service count = 2
Previous Shutdown Cause: 5
NVDANV50HAL loaded and registered.

A Hardware reset COMMAND/OPTION/R/P has resolved the issue.

Well - internally I am not sure.

But aside from the fact it cut off 35 seconds from my POST time when powering on - once into OSX - i loaded LOGIC PRO

and it seemed to have to rescan and ... well - setup all of the internal audio architecture on the machine. Logic took a good 30 seconds sitting there running off all kinds of jargon about audio devices etc etc....

I can't find anything on the web about this hardware reset key combo?!?
