Instability during large transfers

[Jason A. Donenfeld]

Hey Samuel,

Thanks for sticking with it... This is a super hard bug to track down!
I wish I could reproduce it.

Can you try two odd things, separately, and report back?

1. Compile with DEBUG_ATOMIC_SLEEP. Do you get any additional warnings?
2. Hack kernel/sched/Makefile to remove "-fno-omit-frame-pointer" and
see if the backtraces you get are a bit more coherent.

Feel free to find me on IRC.

Jason
