not sure, I'm not setting anything specifically, is this snippet of dmesg relevant:

[ 1.148829] HPET: 8 timers in total, 5 timers will be used for per-cpu timer
[ 1.148934] hpet0: at MMIO 0xfed00000, IRQs 2, 8, 40, 41, 42, 43, 44, 0
[ 1.149331] hpet0: 8 comparators, 64-bit 14.318180 MHz counter
[ 1.151831] hpet: hpet2 irq 40 for MSI
[ 1.151962] hpet: hpet3 irq 41 for MSI
[ 1.155930] hpet: hpet4 irq 42 for MSI
[ 1.159937] hpet: hpet5 irq 43 for MSI
[ 1.163943] hpet: hpet6 irq 44 for MSI
[ 1.175955] Switching to clocksource tsc
so I guess I'm using hpet?
n.
