I can report a "metoo" on this problem (lots of g_vfs_done errors followed by a 
reboot), with 6.2-RELEASE, opteron CPUs running an i386/SMP kernel

Controller Name 	ARC-1160
Firmware Version 	V1.39 2006-1-4
BOOT ROM Version 	V1.39 2006-1-4

All the volumesets are RAID 6

I was doing a buildworld, rsyncing a big tree from another machine, and a 
portsnap extract simultaneously (all as a stress test).  The firmware isn't the 
latest - hadn't upgraded it yet because it seemed to be working fine.
