Without panic messages, its really hard to say. Why don't you pull down
5.2-BETA and see if you can reproduce the issues?

There was an acpi shutdown panic in 5.2 a couple of times, but it seems to
be happy now.

Can't help you on the ehci/umass issue though.  I have a USB disk that
will at least read ok, but since its HFS+ I can't mount it. Its also my
backup disk for my Macs so I'd prefer not to destroy it :-)
