hmmm ...
i am not quite shure that this is only working with an xp processor ... at
the moment i'm looking for some additional informations, how to tune the
processor registers to implement the fix for the errata 11 bug. it must be
possible from within the kernel to do this. you have to modify the
CLK_CTRL MSR to a different value. i hope amd will send me the document
#24478 where the right values are described ...
has someone experiences how to modify msr ? i found 2 assambler commands
("rdmsr/wtmsr") but i have no experiences with assamambler ...
