Interestingly enough, after I had the motherboard replaced, I now experience crashes of (mostly) the AirPort drivers when the machine boots (not when waking up from sleep):
RFpanic(cpu 2 caller 0xffffff80002b93ec): "Spinlock acquisition timed out: lock=0xffffff80008b9500, lock owner thread=0xffffff8011f96580, current_thread: 0xffffff80144125c0, lock owner active on CPU 0x0, current owner: 0xffffff8011f96580"@/SourceCache/xnu/xnu-1699.26.8/osfmk/i386/locks_i386.c:376

I can get around this by booting into single user and doing "fsck -fy && exit" at the root prompt (the machine boots normally).
In addition, kernel_task (PID 0) has a tendency to eat >100% CPU with the fans going all the time (but using gfxCardStatus and switching to the Intel GPU I seem to have this covered). This is on a MBP where the motherboard has been replaced due to the TS4088 (NVidia GPU) issue.
I am also unable to upgrade the EFI to 2.6 (to include "Internet recovery" for Lion).
Has anyone experienced that a reinstall of the OS would fix some/all of this?
