Additionally, USB devices don't get detected. Running a kernel without ACPI solves both these problems. The system is an Athlon 2400+ on a Gibabyte GA-7VAXP mainboard. (KT400) This is from dmesg with ACPI (CONFIG_ACPI=y) enabled: -- ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx VP_IDE: IDE controller at PCI slot 0000:00:11.1 VP_IDE: (ide_setup_pci_device:) Could not enable device. hda: WDC WD800JB-00ETA0, ATA DISK drive -- .. and this is with ACPI (# CONFIG_ACPI is not set) disabled: -- ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx VP_IDE: IDE controller at PCI slot 0000:00:11.1 VP_IDE: chipset revision 6 VP_IDE: not 100% native mode: will probe irqs later ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx VP_IDE: VIA vt8235 (rev 00) IDE UDMA133 controller on pci0000:00:11.1 ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xd808-0xd80f, BIOS settings: hdc:DMA, hdd:pio hda: WDC WD800JB-00ETA0, ATA DISK drive -- I'm happily running without ACPI now, but I guess the kernel just shouldn't be exhibiting the above behaviour. If whomever is fixing this bug needs more and/or more detailed info, please email me and I'll provide it.
