ACPI causes system lockup on Ubuntu 7.10 with Foxconn 945P7AA Motherboard

Bug Description

When booting off Ubuntu Gutsy 7.10 Live CD, my computer quickly locks up, usually before it is completely booted. The furthest I have been successful in booting is about 10-20 seconds past the point where the initial GNOME desktop appears.

If I use the alternate CD, I can successfully install Ubuntu; however, the computer locks up within 10-20 seconds after Gnome loads. Note: If I type Ctrl-Alt-F1 after the computer boots, I can use the computer from the console without Gnome/X-windows loaded, but it will lock up within seconds after I log in from Ctrl-Alt-F7 and load a display manager.

If I boot the Live CD with acpi=off, the computer will boot successfully, and I can install Ubuntu from the graphical installer. Then, if I edit /boot/grub/menu.lst to add "acpi=off" to the boot parameters, the system works fine and is stable.

Notes that may be related to the problem:
    - Version 7.04 would boot and install successfully without the acpi=off switch; however, the system was not very stable. System lockups would occur every 1-3 days, requiring a hard reboot.
    - The last stable version of the kernel that I was able to use with acpi enabled was 2.6.17-14. Instability occurred when I upgraded to the 2.6.20-16 kernel with the Ubuntu 7.04 "Feisty" upgrade. (Note however: a lockup every 1-3 days in 7.04 was much better than within 10-20 seconds under 7.10!)
    - I was able to get Ubuntu Gutsy 7.10 to load with the EVGA nvidia video card below. Originally, I had an ASUS EAX300SE-X/TD/128 Radeon X300SE 128MB 64-bit DDR PCI Express x16 Video Card. With this video card, Ubuntu 7.10 Live CD booted with acpi=off, but the sound card did not initialize correctly and started making horrible buzzing and scratching noises, so I did not proceed with the installation and simply swapped the video card.

Hardware is as follows:
Foxconn 945P7AA-8EKRS2 LGA 775 Intel 945P ATX Intel Motherboard with the following onboard:
    * Intel 945P Chipset
    * ITE8212 Raid Controller (PATA)

I just tried it with 8.10, Intrepid Ibex, and the problem still exists.

It's important to note, however, that there is absolutely no problem if I install with acpi=off, so it seems related to a kernel bug with handling acpi.

I just upgraded to Foxconn's BIOS version 515F1P55.

The problem went away, and the system is stable now with ACPI turned on. I have marked this bug "Invalid", since it seems to have been fixed by Foxconn, so it was probably a bug in their BIOS.

Changed in linux:
status: New → Invalid
