I had tried 3.99.17 from the new restore CD and it would give me the 
same crashes.

I just got 200604250000Z --> 3.99.18 (GENERIC) #0: Tue Apr 25 10:44:05

This one does not crash, however things are not perfect :

pickle ~ # brconfig bridge0 up
pickle ~ # tlp0: transmit timeout
tlp1: transmit timeout
Apr 25 20:33:14 pickle /netbsd tlp0: link state changed to DOWN
Apr 25 20:33:14 pickle /netbsd tlp1: link state changed to DOWN
Apr 25 20:33:16 pickle /netbsd tlp0: link state changed to UP
Apr 25 20:33:16 pickle /netbsd tlp0: link state changed to UP
tlp0: transmit timeout
Apr 25 20:34:33 pickle /netbsd tlp0: link state changed to DOWN
Apr 25 20:34:33 pickle /netbsd tlp0: link state changed to UP
tlp0: transmit timeout
Apr 25 20:34:40 pickle /netbsd tlp0: link state changed to DOWN
Apr 25 20:34:43 pickle /netbsd tlp0: link state changed to UP

Once it does that, tlp0 and tlp1 randomly stop working until a reboot 
(happened 3 out of 4 tries). The warnings always show up though.
