I have the same here on HP Pavilion dv6840ew (amd64, nvidia). I wouldn't recommend using "acpi=noirq" - it "solved" the issue, but I haven't been able to start X using proprietary Nvidia driver. Then I tried using nv instead and started X, but strange things happened - e.g. when I connected to wireless network (using proprietary broadcom driver), the mouse cursor stopped responding, then keyboard, and soon I was left with only one option - hard reset. I've tried it again then and got the same results.
I've also tried other mentioned options - "nolapic", "nosmp" and "hpet=disable" - at this point I can say that each worked and I haven't noticed any side effects, but I really can't say for sure that there aren't any. For now I'll stick to "hpet=disable" and if I notice some strange behavior I'll post about it here. -- System freezes during boot, unless I hold a key down https://bugs.launchpad.net/bugs/272247 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
