    Subject"double" hpet clocksource && hard freeze [bisected]
    Hi,

    since commit:

    commit 0aa366f351d044703e25c8425e508170e80d83b1
    Author: Tony Luck <tony.luck@intel.com>

    [IA64] Convert to generic timekeeping/clocksource

    This is a merge of Peter Keilty's initial patch (which was
    revived by Bob Picco) for this with Hidetoshi Seto's fixes
    and scaling improvements.


    I have a double "hpet" entry in "available_clocksource":
    $ cat /sys/devices/system/clocksource/clocksource0/available_clocksource
    tsc hpet hpet acpi_pm jiffies


    And, more interesting, if I select hpet as clocksource (tsc is used by
    default here) I get an hard freeze some time later (few minutes)...
    SysRQ don't work ;)


    config & dmesg attached
