I may be having the same problem on gutsy x86 on a Core 2 Duo T7200 Toshiba laptop.
In my case the linux-image-xen kernel boots fine as long as the virtualization support is turned off in the BIOS, but when I turn it on in the BIOS, boot on dom0 hangs. The last console output is: Setting up standard PCI resources I note that on a successful boot, this line comes right before some ACPI stuff: ACPI: EC: Look up EC in DSDT ACPI: Interpreter enabled ACPI: (supports S0 S3 S4 S5) ACPI: Using IOAPIC for interrupt routing I'll be trying to boot with ACPI off next. -- Hangs at boot on AMD64 https://bugs.launchpad.net/bugs/65788 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
