Crash with heavy ZFS I/O (current of today)

Greetings,
    I seem to have found an issue with a kernel from today.  Last "good"
kernel was from 2009-05-08 or so.
    What I see is while Bacula is doing a differential backup the wired
memory goes up to 3.3G (I have 4G real), and we start paging like
crazy, and then we panic in ZFS's write routine.
    The system doesn't get all the way into the debugger, and doesn't
get the entire panic out, nor does it cut a dump.

    Any ideas?

dmesg attached.
