Public bug reported: I am booting live cd of Ubuntu 13.10 Desktop 64bit but it ends with kernel panic because of some issues with acpi. I tried the following: - when I provide parameter acpi=off it boots ok. - when I provide acpi=ht (or no parameter) it generates kernel panic (see the screenshot in attachment).
Moreover I can run 32bit version of Mint 15 with no acpi issues which suggests that only 64bit version is affected. There is attachment with two subdirectories: one contains data from Ubuntu 13.10 64 bits livecd taken with acpi=off and the second taken from 32bit version Mint 15. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: 13.10 acpi ** Attachment added: "acpi.zip" https://bugs.launchpad.net/bugs/1243431/+attachment/3887836/+files/acpi.zip ** Tags added: 13.10 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1243431 Title: Ubuntu 13.10 64bit livecd won't boot unless acpi=off on Dell Optiplex 745 Status in “linux” package in Ubuntu: New Bug description: I am booting live cd of Ubuntu 13.10 Desktop 64bit but it ends with kernel panic because of some issues with acpi.
