Re: Another CPU slows to a crawl after resume from suspend

   Have you tried running the "bogomips" userspace program to re-check your
   system speed?  Also, try running 'date' a lot of times and see if seconds
   are counting at the right rate.

AHA!  The system date is running at about 1/6 normal speed.  Running
bogomips before a suspend returns a value of 466.00 BogoMips (normal for a
233MHz MMX).  Running bogomips after resume from suspend fails:

    sohpia> bogomips
    Calibrating delay loop.. failed

Whoops.

   I don't know of any quick cpu-speed-reset programs.  Maybe "apm --standby"
   will kick things and make them better?

I tried this and got:

  apm: standby: Unable to enter requested state

So, looking at the source for bogomips, it looks like when it fails, the
implication is that the system timer is running too slowly.  Is this what
you'd conclude as well?

    - pz.
