Hi Takashi,
Thanks for your reply.
Did you enable HPET?
Hmm, it seems so... I configured my kernel using the debian .config
as oldconfig.
$ grep HPET /boot/config-2.6.10-ck2-pentium4
CONFIG_HPET_TIMER=y
CONFIG_HPET=y
# CONFIG_HPET_RTC_IRQ is not set
CONFIG_HPET_MMAP=y
When hpet timer is enabled, it disables RTC
interrupts.
Ah, even when CONFIG_HPET_RTC_IRQ is not set??
Even worse, it disables RTC irq even if HPET is not
detected from BIOS but only compiled.
I see... Ok, I will recompile my kernel with HPET disabled.
But maybe a HPET version of the latencytest would be nice,
especially since:
"The High Precision Event Timer (HPET) hardware is the future
replacement for the 8254 and Real Time Clock (RTC) periodic timer
functionality."
