It happened with earlier kernels as well. > please try 2.6.29. I will try. > please try it with CONFIG_HWMON=3Dn Would that be only a workaround or a solution? As a workaround I use thermal.nocrt=3D1 (or options thermal nocrt=3D1). Should I try both 2.6.29 and CONFIG_HWMON=3Dn? > If it still fails, please file a bugzilla > http://bugzilla.kernel.org/enter_bug.cgi?product=3DACPI > and attach the acpidump there. I will as soon as I will have tried the options.
