NAK!

If the HPET is unreliable on a specific platform then any of the 
following solutions would address the problem (in order of 
preference):

 - the hardware should not expose it. Why waste silicon on something 
   that does not work?

 - or the firmware should not expose it. Why expose something that 
   does not work?

 - or the kernel should have a quirk to reliably disable it. Why 
   should we crash or misbehave if a driver is built into the
   kernel?

tweaking a default is _NOT_ a solution for an unreliable hpet.

Thanks,
