Trouble with amd64

[Doug White]

Since this references 6.0-RELEASE it should have been sent to -stable, or
since it references amd64 specifically it should have been sent to -amd64.
Rerouting to -stable.

According to the code this panic occurs when there is a problem with the
DMA memory management. Typically we see this when the driver is not 64-bit
clean, but I'd find that hard to believe with amd64 since the same driver
runs on sparc64 fine (and must since many Sun machines have embedded sym
controllers).

Unfortunately it doesn't help that the sym driver has its own bizarre DMA
management. It uses busdma but its kinda bolted on over the old
memory-block management. Not going to make it any easier to debug.

Can we get the dmesg from this system?
