I noticed while scanning through my dmesg that acpi_hpet0 gets found twice during bootup: the first time it fails to attach because it never increments, but the second time around it works and is chosen as the primary timecounter: acpi0: <HPQOEM SLIC-MPC> on motherboard acpi0: [ITHREAD] acpi0: Power Button (fixed) Timecounter "ACPI-safe" frequency 3579545 Hz quality 850 acpi_timer0: <32-bit timer at 3.579545MHz> port 0x408-0x40b on acpi0 acpi_ec0: <Embedded Controller: GPE 0x3> port 0x62,0x66 on acpi0 acpi_hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed003ff on acpi0 acpi_hpet0: HPET never increments, disabling device_attach: acpi_hpet0 attach returned 6 acpi_button0: <Power Button> on acpi0 Then a bit later: battery0: <ACPI Control Method Battery> on acpi0 cpu0: <ACPI CPU> on acpi0 acpi_throttle0: <ACPI CPU Throttling> on cpu0 cpu1: <ACPI CPU> on acpi0 acpi_hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed003ff on acpi0 Timecounter "HPET" frequency 14318180 Hz quality 900 Is this expected? -- Bruce Cran <cid:part1.07030001.01090502_at_cran.org.uk> Copyright (c) 1992-2008 The FreeBSD Project.
