** Attachment added: "Kernel config" http://launchpadlibrarian.net/8103654/2621-HP.config
** Description changed: Whether 64-bit or i386, custom compiled or stock kernel, setup or actually in the distro, Ubuntu requires either noapic or pci=noacpi. That presents problems and trade-offs that don't make Ubuntu a viable option. Slackware works without the need to disable anything, and according to a Gentoo user on Linux on Laptops, neither does Gentoo. - This is the working config I use in Slackware that I also used in - Ubuntu: http://red.caek.org/2621-HP.config - - With the default parameters, Ubuntu will freeze as it loads GDM, so it - hangs at a black screen. In single user mode, with apic enabled, it will - still freeze. Without quiet nosplash it might hang at loading the - drivers or "setting up console font and keymap". + This is the working config I use in Slackware that I also used in Ubuntu: 2621-HP.config + With the default parameters, Ubuntu will freeze as it loads GDM, so it hangs at a black screen. In single user mode, with apic enabled, it will still freeze. Without quiet nosplash it might hang at loading the drivers or "setting up console font and keymap". If I disable apic, change xorg.conf to use the vesa driver, then boot normally, loading GDM no longer results in a black screen, it actually comes up and I can log in. However, it still freezes completely about a minute or two after. 'noapic' = Ok, the machine boots, everything works, except for USB. So adding irqpoll will fix the USB problem. 'noapic irqpoll' / 'noapic irqpoll noirqdebug' = Machine boots, but there doesn't seem to be any power management or cpu frequency scaling. The CPUs are constantly running at full speed. No battery detection, etc etc. 'pci=noacpi' = Big fat X11 error message trying to use the accelerated nVidia driver, a problem relating to edge-triggered IRQs. I'd like to stick with Slackware, but I need a distro with a package manager. I have some logs zipped up, including from Slackware, and lspci -vvvv from Slackware. I hope they're enough to go on.
