Description

Hi.
I caught this panic while running pbulk and vkernel on the same machine.
The PC has 1.5G bytes of main memory, occasionally using the swap up to
20M or so bytes (according to top).
The kernel is built from source as of cf0e75a4(+ small modifications not
touching the kernel). I've turned off periodic/daily/160.clean-hammer
and run `hammer cleanup /pfs/*' by hand only occasionally (but I'm sure
I can't fill up this 1TB hard drive anyway). The hammer filesystem version
is 2. I'll upload the vmcore to leaf on request.

Cheers.
