When they're running on battery there's no problem with performance... but when you plug them in again the performance decreases rapidly... we've found a solution on the linux-club forum: http://www.linux-club.de/viewtopic.php?p=456891#456891 the failure is because of the smp kernel which is integrated into the kernel, and so the notebooks choose a false mode for it.. when you deactivate smp in the kernel and compile it new the problem is solved.. so maybe there's a possibility to detect whether it's an asus notebook and therefore deactivate smp. Steps to reproduce: everytime (during boot, work, simply everytime) ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
