I finally got Linux and BusyBox booting on my board, but I've encountered a
fairly odd problem... any task that sleeps just goes dead entirely, never
resuming. If I enable networking support, this seems to happen before init is
even spawned (in this case, inside cpu_idle() according to remote gdb).
I'm guessing interrupts aren't firing for some reason, but does anyone else
have any ideas? Maybe this is more obvious/common than I'm guessing.
Thanks,
Luke

Try irqpoll? nohz=off?
