@Napoleon: thanks for feedback and well, this workaround was intended to fix only hangs on rebooting on some hardware (like Dell): as you found it doesn't fix shutdown hangs.
@Christopher: I found no way to capture an OOPS. I installed linux- crashdump and rebooted (reproducing a hang), but I can't find an OOPS dump. However I'm attaching the current logs. Please tell if there's anything else I can do. Thanks. ** Attachment added: "logs.7z" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/985471/+attachment/3103051/+files/logs.7z -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/985471 Title: Ubuntu precise (12.04) 64bit hang on reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/985471/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
