Intriguing about the broadcom driver relationship.

I find humor in the brcm log entries:

[   15.290813] brcm80211: module is from the staging directory, the
quality is unknown, you have been warned.


Anyway here is the first error encountered by your system:

I'm not really familiar with wireless network kernel driver debugging
but it looks like this is something in the wireless stack.  There
follows a bunch of other kernel errors in the logs.

The X fault may simply be a side effect of your system being in such an
inconsistent state after the wireless failure.

** Summary changed:

- [arrandale] GPU lockup (ESR: 0x00000001 IPEHR: 0x08914160)
+ [arrandale] GPU lockup (ESR: 0x00000001 IPEHR: 0x08914160) - broadcomm wireless conflict?
