1996 22:13:07 -0700 OK.  I've let the machine run overnight (and
it didn't ever finish). The problem is that it is stuck in the
following kernel code:          printk("Calibrating delay loop..
");         while (loops_per_sec <<= 1) {                 /*
wait for "start of" clock tick */                 ticks =
jiffies;                 while (ticks == jiffies)
printk("Jiffies = %d\r", jiffies ) /* nothing */;
/* Go .. */                 ticks = jiffies;
ticks = jiffies - ticks;                 if (ticks)  Will just
print Jiffies = 0 forever :-(  I'm at a loss to understand why
this is happening to me.  The declaration looks correct to me:
include/linux/sched.h: extern unsigned long volatile jiffies;
so it likely is the case that I'm not taking interrupts that
cause the jiffies count to be incremented.  Any ideas on what to
look for?  I've gone ahead an
