Subject: Re: [PATCH] x86/hpet: prevent boot hang when hpet=force used on old ICH

Ingo,
Thanks for the reply.

But please disregard that patch -- we've cooked up a better one
that allows ICH4M to continue to use hpet=force, even for clocksource.
(and it is an ACPI patch rather than an x86 patch:-)

However, I'll also send a 2nd patch to stop soliciting more hpet=force
users, since technically we shouldn't be encouraging the use of
this un-documented and lightly-validated hardware.

thanks,
Len Brown, Intel Open Source Technology Center
