At this point, the only fix i have is to "reboot"... There's
something seriously wrong with the original Panda with the mainline
kernel past v3.2.x.. I haven't found a solution yet for this...

Really? same "abort" [Unhandled fault: imprecise external abort
(0x1406) at random_address] message? then maybe its one of the config
options that's causing it.. (can you share with me your v3.2.x config)
As my v3.2.x works just fine, so i can compare the two....
