Thinkpad W520 - 4270CTO (Nvidia Quadro 1000M - 4 Gb RAM - nouveau) BIOS version 8BET50WW ( 1.30 ) - latest on lenovo's site (setup UEFI boot - BIOS set to UEFI only)
If I disable VT-d extensions in the BIOS, then I don't need to set pci=noacpi to prevent crashes. (vmx is still enabled.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776999 Title: [Lenovo W520] laptop freezes on ACPI-related actions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/776999/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
