Will not provide with full listings but just a diff comparing two
states (this good one with HPET working and bad w/o it):
rainhaven# diff devinfo.r.good devinfo.r.bad
177,179d176
< acpi_hpet0
< I/O memory addresses:
< 0xfed00000-0xfed003ff
rainhaven# diff devinfo.u.good devinfo.u.bad
128c128
< 0xfed00000-0xfed003ff (acpi_hpet0)

> 0xfed00000-0xfed003ff (ichsmb0)
So kernel with 1.243.2.3 revision of /usr/src/sys/dev/acpica/acpi.c
allocates the region required to ichsmb0 instead HPET (it not helps to
ichsmb0 because it never was working on my laptop but it is another
story I think).
Thank you for looking into.
Hmm, so ichsmb0 doesn't show up at all in your earlier dmesg. Try this
It never was working for me. Well nothing more than
ichsmb0: <SMBus controller> port 0xb00-0xb0f mem 0xfed00000-0xfed003ff
at device 20.0 on pci0
ichsmb0: can't map I/O
device_attach: ichsmb0 attach returned 6
change, it restores the probe orders to be more of what they used to be and
just gives CPUs a really high probe order so that they should be after other
devices.
It was the patch against the CURRENT as far I understand while my
laptop running 7.0-STABLE. Well it was applied manually (not a so big
issue finally) against 1.243.2.3 revision of
/usr/src/sys/dev/acpica/acpi.c and reporting success for the HPET
functionality at least (part of relevant verbose dmesg output):
ACPI: HPET @ 0x0x77fd6800/0x0038 (v 1 A M I OEMHPET 0x10000626 MSFT
0x00000097)
acpi_hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed003ff on acpi0
acpi_hpet0: vend: 0x4353 rev: 0x10 num: 3 hz: 14318180 opts: legacy_route
Timecounter "HPET" frequency 14318180 Hz quality 900
And part of sysctl variables related:
kern.timecounter.choice: TSC(800) HPET(900) ACPI-safe(850) i8254(0)
dummy(-1000000)
kern.timecounter.hardware: HPET
I/O mem conflict with ichsmb still in place though
Thank you
