5.4-RC3 hung - DDB trace/ps provided [was 5.4-RC1 Freezing, butpingable (may be related to gvinum)

Ever since installing 5.4 on this machine, it has been frequently 
locking up. This machine was running 5.3-RELEASE for several months 
without exhibiting similar symptoms.

The machine becomes unresponsive to console and TCP connections (ssh), 
however remains pingable.

This last time I left it alone for several (15-20) minutes after 
breaking to DDB to get a trace and it actually came back to life. This 
behavior is different than what I experienced with 5.4-Beta1 and 
5.4-RC2, where it would hang for an indefinite period of time (i.e hours 
before I would reboot).

I've included copies of ddb's ps output and a dmesg as attachments. Here 
is a trace (pid 95 is bufdaemon):
