Solution: Disable special CPU/motherboard/IO services. I mean: append kernel parameters with this: acpi = off noapic nolapic This can be done before booting, but it's the best to create a new, "safe system start" entry in your grub menu (read manual to do this).
For me this always solved the problem, but it was never a complete solution, because other new problems occured: 1. No more wireless LAN support; 2. Ubuntu is no longer able to turn computer off when trying to; 3. USB devices working slower, especially when connecting USB 2.0 device on USB 1.0 port; this means an exponential-slowing-down. I haven't test it with wired LAN, but it may be affected too. If you can live with these limitations then your system will be atomic-secure and stable, but your system will feel like an old 3.86/4.86 PC in the 90's. I wonder when this bug will be fixed finally, because I might have given enough informations about the source of the problem in the beginning of this comment (IO/APIC). -- Random system freeze at window operations https://bugs.launchpad.net/bugs/62747 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
