Sorry, the system has 2 Dual core opterons, not 4 cpus. Anyway i've tried it on a third machine with dual core opterons and it hanghed there too.
The latest messages I see are: Initializing CPU#1 Initializing CPU#2 Brought up 4 CPUs Initializing CPU#3 migration_cost=522 Grant table initialized NET: registered protocol 16 ACPI: bus type pci registered PCI: Using configuration type 1 And nothing more. The same happened on these three dual-cpu system while 2.6.16 works well instead (tried it loading almost 8 virtual machines). Any idea? -- Hangs at boot on AMD64 https://launchpad.net/bugs/65788 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
