Subject: [Bugme-new] [Bug 8193] New: Asus Notebooks only have full power off the dc

http://bugzilla.kernel.org/show_bug.cgi?id=8193

Summary: Asus Notebooks only have full power off the dc
Kernel Version: 2.6.20-2 (but in all kernel releases)
Status: NEW
Severity: high
Owner: [email protected]
Submitter: [email protected]

Most recent kernel where this bug did *NOT* occur: there's no kernel without this bug
Distribution: openSUSE 10.2, mandriva 2007
Hardware Environment: Asus Z9252Va, but this affects most Asus Notebooks (and some others (sony vaio)
Software Environment:
Problem Description: The notebooks are really slow when they are plugged in. 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)
