>Description:
When copying data from one filesystem to another (in this particular case, it happens to be with either dd or rsync from /usr to a filesystem living on a gvinum volume, but gvinum doesn't seem to be implicated), machine crashes with following trace. First two lines are through dmesg, then the debugger kicks in:

Unfortunately, I haven't been able to get a crash dump: calling doadump prints a claim that it's outputting to disk, but no data actually gets written. I haven't looked into this deeply, yet.

>How-To-Repeat:
Copy data from one filesystem to another. Reliably fails on an 8-GB transfer, but does not seem to occur at any particular point in the fs or after any particular interval. This happened under 6.0-BETA3, so I tried updating to the latest RELENG_6 CVS and rebuilt the kernel, to no avail.
