 Seems to be the cause.  If I make "needsoftclock" be always true in  
 kern_timeout.c:callout_hardclock, the machine works fine.  Similarly,  
 adding "_setsoftintr(0)" just after the call to hardclock() from  
 clockintr() does the same.
 
 Otherwise, at some point the machine seems to stop receiving  
 interrupts: not even clockintr is called.  See my last reply to the PR.
 
 I'm at loss on how to debug this.  Any hints please? :-)
 
 Thanks,
