Under heavy load, and after several hours of building packages, I am seeing the following crash. I'm doing a bisect to narrow down more, but it has been happening at least a week ago, with kernel and all modules build from sources updated on 2015-10-13 at 08:30:00 UTC. (This is on amd64) Here's the backtrace from gdb:

This looks like one of the crashes riz@ had on a tegra which I think was also
building packages.
=> 0xffffffff80333415 <+59>: mov (%rax),%rdx
I think %rax will be "weird" and indicate pool_head list corruption - no idea why, though.
