 Does it still crash if you disable azalia? (with boot -c)
 
 If not, the best approach is probably to disable azalia while
 installing, then try a kernel from the netbsd-5 branch (5.0_STABLE
 rather than 5.0.1 or 5.0.1_PATCH) which will have the replacement
 hdaudio(4) driver instead, which works a lot better and will hopefully
 not crash.
 
 If the crash still happens that way, it's something else causing it,
 and the first step is to extract a stack backtrace from ddb (type
 "bt") to see where it blew up.
