I think this may have been my own mistake. In between all the kernel compiles, I seem to have managed to do the following: # CONFIG_X86_PM_TIMER is not set Which was probably the cause. (was getting other side effects too, like keys stuck in repeat, 1-2 second freezes etc etc) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
