I suspend my machine (a Thinkpad T21) often -- many times a day.  It 
almost always works, and most of the time when it doesn't I have the 
advance warning of error messages from the sound card driver during the 
previous resume.  However, at the last three 'suspend' operations the 
machine has wedged solid, with no warnings.  Any theories?  I'm running 
1.5.2alpha as of July 31; I even went to the trouble of cmp'ing /netbsd 
with the /sys/arch/i386/compile version.
