--- Comment #7 from Rick Macklem <rmacklem at FreeBSD.org> ---
I tested the keg_drain patch and got a panic.
The panic string appears to be just "page fault"?
It happens in:
zone_reclaim(0) at zone_reclaim+0x1ee/frame 0xe596a9c
Does this mean that the "struct uma_zone *" argument was NULL?
It took a couple of hours of kernel building to cause the panic.
