I'm setting up this SMP amd64 system, now running the i386 port, -current
kernel and binaries built yesterday.

I have a large raidframe "disk" (raid1, two SATA disks).  I used tar

raid disk.  The source files were read over NFS.  Nothing else (but
systat) was running on the system.

without raidframe, so this is not a new problem.  I'll try to do more
testing when I get back to the new machine (it's kind of slow over
