tom01 Posted September 6, 2008 Share Posted September 6, 2008 (edited) Right, I'm tired of trying every distro now to see if any support my laptop with power management...Each time I boot Ubuntu I get MP-BIOS bug: 8254 timer not connected to IO-APIC Is their actually any "fixes" to get this working so I can see my battery level? I don't want to use "noapic" in the Grub menu. Everything is fine with the AC is plugged in but the GUI goes slow when on the battery? tom@ubuntu:~$ dmesg | grep timer [ 0.004019] Calibrating delay loop (skipped), value calculated using timer frequency.. 3192.15 BogoMIPS (lpj=6384316) [ 0.904031] ..MP-BIOS bug: 8254 timer not connected to IO-APIC [ 0.904031] ...trying to set up timer (IRQ0) through the 8259A ...

lusbyjeff Posted November 27, 2008 Share Posted November 27, 2008 hey tom i have the averatec 6200 and am having the same problem with the noapic thing and ubuntu. i know for sure that suse linux enterprise desktop 10 and turbo linux fuji work on these laptops. installation is a breeze with both and no noapic issues. seems to me that i also had red hat installed on the laptop too at one point and had no probs. good luck jw p.s. have you found any fixes to the 8254 issue?
