Soekris 4826 USB failure on FreeBSD 7.0

[Geoffrey Mainland]

Wow, this turns out to be much worse than I thought...I've tracked down
the problem to the commit of the new physical memory allocator at Sat
Jun 16 04:57:05 2007 UTC. Before that, no kern/122380; after that,
kern/122380 applies. Any ideas where to go from here?

Thanks,
Geoff
