MacBook Air kernel panic!

What should I do? I just got my new MBA, and it's the fourth time, when I got a kernel panic. It happends when I don't use my computer for a while, suddenly, when I try to put it back on it shows me "Your computer had to reboot" or something like that. Here's the log, HELP ME!

I'm not sure what is causing it, but it definitely shouldn't be happening.

Did you clone or transfer everything including files and settings from an older Mac? If so, and you have backups of everything, you could try using the system restore function to get a clean install of Mac OS, and then reinstall the apps and transfer your data separately.

Otherwise, a trip to your local Apple store is necessary...

If it's brand new, it could be a bad logic board. That happened to me once. I'd suggest a trip to the Genius Bar. They can run some diagnostics that could rule in or rule out a hardware issue.

Also check the crash log. Go into Finder, hold down the Option key, and select Library from the Go menu. Within the Logs folder, look in the CrashReporter folder to see if there is a log file. If so, open it up and see if it provides any clues as to whether an application caused the error.

don't think I'm being smart but it is either a hardware or software issue.

possible faulty logic board as already suggested but more likely software.
you could try an erase and fresh install of the OS to determine this - or run diagnostics test to see if it's hardware related - logic board or memory.

this is what Apple Store will do for you anyway so your best bet would be to make an appointment and take it in if you're not confident of doing it yourself.

You are 3/4 correct; a kernel panic is either a hardware issue or a driver issue. A clean reinstall should eliminate it as being a driver issue. It is most likely not a app-related software issue at all. Once you are at that point (after a reinstall), only hdwe is left.

It shows the last loaded kext as Avast AV. I would uninstall Avast AV and see if that helps.

It is definitely logic board problem.

Kernel Panics

so far on, thanks for the help...

I went into Console and Systems Diagnostic reports and looked through all of them and all of them have one of these two last loaded kexts:

last loaded kext at 5446925754: com.avast.PacketForwarder 1.3 (addr 0xffffff7f80abb000, size 20480)


last loaded kext at 335801153215: com.apple.filesystems.smbfs 1.7.2 (addr 0xffffff7f80795000, size 241664)

I think that means that these are two different kernel panics happening.
I have also noticed, that the two happen when I do different things, the avast one when the computer is in standby for a long time and I wake it up (it doesn't happen every time I do it, only sometimes) and the second one, when my MBA goes into screensaver and later, after the number of minutes I have set in preferences it goes into standby - when I wake it up just after that happens.

Thanks for all the help so far, however I hope to get some help on the second panic (I have found on another forum, that Avast has not been updated to Lion, so I hope that if I uninstall it when I find some time that panic will go away) - I'm waiting for your help to find the faulty application that's causing those kernel panics grrrr....

You return it to apple.

Kernel panics are generally hardware (more often) or driver related (if it is driver related, everyone with the same combination of hardware and driver as you will be able to replicate the problem as it will affect them as well).

If its brand new, it certainly shouldn't be doing that and my bet is DOA hardware - looking at the backtrace - it looks like it is crashing in the GPU driver, which means either a bug in the driver or broken hardware.

If it was a bug in the driver, everyone with a new MBA would be seeing similar issues with the software you were running at the time.

The fact you are getting different panic messages also tends to indicate hardware flakiness rather than a particular software bug causing the problem.

It happens... sometimes you luck out and get a broken machine out of the box.

Take it back.

That said, uninstalling avast can't hurt as it is easily done, but i wouldn't waste any more time on it than that. This is the sort of thing your 90 day free support/applecare is for.
