My curiosity got the best of me, and I installed anyway... is there
anyway to determine what is causing the lock-up and eliminate it from
within a running NetBSD system?

My problem now is everything is incredibly slow... partitioning
probably took 15 to 30 minutes, generating RSA/DSA keys for SSH took
several minutes, compiling is painfully slow, and I can't get more
than 500KB/s from the network where I've topped 10MB/s in the past
(same hardware setup but with FreeBSD or Linux on the laptop). I tried
OpenBSD 3.8 a while back, too, and speed was just as bad there. What
might cause this? Is there a way for me to find out (and hopefully fix
it)?
