But anyway, as far as I can tell from my own machine, the _CRS in the
DSDT table never lists the HPET interrupts, and the HPET registration is
always done by hpet_reserve_platform_timers() in arch/x86/kernel/hpet.c.
Try adding logging to hpet_late_init() to find out why it aborts.

I assume you mean in kernel source code?

I'm using distro packages for both kernel & Xen -- not DIY building.
