I had also this problem. The system was just hanging. I used the noapic kernel parameter to bypass this error at boot time, but then the system continued to crash. So, I disabled the cpufreq service and that's it! It now works fine with full acpi support. -- MP-BIOS bug : 8254 timer not connected to IO-APIC https://bugs.launchpad.net/bugs/41095 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
