Hello,
I have (a long-lasting) problem to get hpet attached to a Tyan S3992-E
MB. My last known working kernel is 7.1-PRERELEASE Sep 2 2008" , I
rarely cared about this board for a while...
At that time the dmesg said :
acpi_hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed003ff
on acpi0
Timecounter "HPET" frequency 25000000 Hz quality 900
now it says (debug.acpi.hpet_test="1", debug.acpi.layer="ACPI_TIMER",
debug.acpi.level="ACPI_LV_ALL_EXCEPTIONS" enabled) :
hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed03fff on
acpi0
hpet0: vendor 0xffff, rev 0xff, 232831Hz 64bit, 32 timers, legacy route

hpet0: time per call: 0 ns
hpet0: HPET never increments, disabling
device_attach: hpet0 attach returned 6
Some things strike me :
'vendor 0xffff, rev 0xf' and '4294967295 (== 0xffffffff)' as well
as 232831Hz
the change in iomem range :
OK : iomem 0xfed00000-0xfed003ff
KO : iomem 0xfed00000-0xfed03fff
^^^^
I can provide full dmesg and/or other extra needed info.
Merci, Arno
