I still get "tsc unstable" messages, they don't seem to be the cause of 
the problem.

I only reboot when necessary.  My notebook is usually up between 4 days 
and two weeks at a time.  The phantom interrupts have never reappeared 
after I sorted it out.  I started debugging the problem on a 2.6.21.x.  
Now I'm on 2.6.22.x.  The problem was equally visible on both of those 
kernel revs.

I agree.  I was very frustrated with the problem.
