Created attachment 326225 [details] RHEL5 initial patch for this issue Description of problem: x86_64 uses nopmtimer, nohpet, and notsc to control which clock is used for the GTOD clock. i386 uses "clock=[hpet|pmtmr|tsc]" to control which clock is used for both the wall and the GTOD clock. Make them consistent between arches. Version-Release number of selected component (if applicable): -125.el5 Additional info: Attached patch tested on an xw9400 with HPET enabled in BIOS on both x86_64 and i386 arches.
Quick note on the patch, disable_pmtmr() is not upstream -- I have just pushed a patch to add it upstream. P.
