Description Daniele Rondina 2010-04-11 09:36:12 UTC
Hi, i have a DELL Precision M6500 and it seems that HPET module is broken. Same problem with previous version 2.6.32.

I don't know if it is correct insert this bug on this section, sorry in advance for wrong section.

I'm currently use vanilla sources with gentoo patches.

Bye
