I didn't try that, but I bisected it in the meantime which lead to:

commit 64ce4c2f5252f25798117fa80a027993163d6d84
Author: John Stultz <johnstul@us.ibm.com>
Date: Thu Mar 11 14:04:47 2010 -0800

time: Clean up warp_clock()

warp_clock() currently accesses timekeeping internal state directly, which
is unnecessary. Convert it to use the proper timekeeping interfaces.

So I don't think it's an hpet issue. :-)

I'm now going to revert that commit and see what happens.

Thanks,
Rafael
