If booted up from a usb flash drive and then attempting to sleep (acpi state 3) 
the kernel crashes whilst trying to synchronize the cache.

The following was obtained from the crash:

Flushing disk caches done.
umass generic HBA error.
sd0 cache synchronization failed.

It then drops into ddb where I obtained the following back trace:

page fault type 6 code 0 eip 0 invalid address

This problem has been bugging me for a while.  It did not occur in NetBSD 5.0.1.

The usb device still has power to it whilst this occurs (there is an indicator 

I can shutdown ok, it just crashes while attempting to suspend.

Boot up from an installation on a usb flash drive and try to suspend (acpi 
state 3).
