(and for eventual .26 and .25 backporting, if it's simple enough) first thing would be to check whether tip/master works fine: http://people.redhat.com/mingo/tip.git/README if that works fine it would be nice to check whether the pending changes in tip/timers/hpet solves this particular issue. That can be done by: git-checkout -b tmp.test tip/timers/hpet [ once you have set up tip as a remote repository, as described in the README above. ] If tip/timers/hpet solves the problem then it's one of these five commits that solves it: f92a789: hpet: /dev/hpet - fixes and cleanup, fix 64a76f6: hpet: /dev/hpet - fixes and cleanup f356181: x86: add PCI ID for 6300ESB force hpet 3243b4e: x86: add another PCI ID for ICH6 force-hpet 70ef6d5: x86: get irq for hpet timer Ingo -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
