I too am affected by this bug (exactly as reported by pnp6nl). Trying to install 11.04, 64bit from DVD.
I have a Toshiba satellite Pro, Intel Core Duo P8400, Radeon 3400. I get the flash screen then it dies. If I press F6, then I get the choice of language and the initial menu. I have tried various ACPI settings but whatever I do, the system crashes soon after I select Install. I have also tried various BIOS settings and some of the above suggestions. There seems to be no way of setting pcie_aspm=off in the BIOS. If it helps I will get a log file / dmesg but I expect you know the problem by now. Pity there is no work around after 5 months. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/763909 Title: 11.04 Wont Boot With Mobility Radeon HD 3400 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/763909/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
