So done some more digging into the problem. I found the page at: https://01.org/linux-acpi/documentation/debug-how-isolate-linux-acpi-issues
I decided to try them all and see the effects. It went like this: * acpi=off - Works, but looks terrible, trackpad doesnt work, keyboard spams keys randomly when pressed, unless you can press and release the key in like 1 millisecond. * acpi=ht - Same as without nolapic. * pci=noacpi - Says it gave up waiting on root device. That "/dev/disk/by-uuid/*kUbuntu's uuid*" does not exist. (got a pic) * acpi=noirq - Same as without nolapic. * pnpacpi=off - 1st attempt, froze at an apparently random point in bootup, touchpad on last line. 2nd attempt, kernel panic - not syncing (got a pic), 3rd attempt, froze at what seems to be the same point as attempt 1 (got a pic). 4th attempt, got to login screen then did the usual freeze. 5th attempt, same as 4th but the bootup was in the correct resolution. nice small text instead of huge zoomed in text. * noapic - 1st attempt, stalled at bootup, 2nd attempt, got to login screen then the the usual freeze after 8ish seconds, 3rd attempt, same again exept froze almost instantly. * nolapic - Always works. Is what my default boot options are set to. But performance suffers since then it only uses 1 cpu core. There is another image of it booting but I forgot to name it with the options I used. Its another kernel panic. I then tried about 6 times to get as far as logging into tty1. Eventually I was lucky and quick enough to get in. After doing a quick cpuinfo to see the 6 cores working it froze again. But with a message! Another kernel panic. I think this might be the issue: "Kernel panic - not syncing: Timeout synchronizing machine check over CPUs" Pic of pci=noacpi - http://i294.photobucket.com/albums/mm82/cgar_of_ayr/linux%20boot%20errors/pcinoacpi.jpg Pic of 2nd pnpacpi=off attempt - http://i294.photobucket.com/albums/mm82/cgar_of_ayr/linux%20boot%20errors/pnpacpioff_2.jpg Pic of 2nd pnpacpi=off attempt - http://i294.photobucket.com/albums/mm82/cgar_of_ayr/linux%20boot%20errors/pnpacpioff_3.jpg Pic of unknown option error - http://i294.photobucket.com/albums/mm82/cgar_of_ayr/linux%20boot%20errors/anotherPanic.jpg Pic of it failing after logging in with no boot options - http://i294.photobucket.com/albums/mm82/cgar_of_ayr/linux%20boot%20errors/noParams.jpg This help anyone think what it might be? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1336451 Title: Cannot boot/run ubuntu without acpi=off or nolapic.
