Ok, this is _exactly_ the same problem I have.  UP or MP makes no 
difference.  Sometimes I get a "Level 15 Interrupt", sometimes "Watchdog 
Reset"...  When I run under X, is crashes when doing for instance an 
untar of pkgsrc.tar.gz, when not using X, everything seems to run 
smooth.  So I thought that my cg14 is/was broken...

So, actually, this might be NetBSD bug?  How can I help in solving it?
