http://cgit.freedesktop.org/systemd/systemd/commit?id=bf7f800f > After a recent change present in 3.11-rc1 there is a driver, called processor, > that can be bound to the CPU devices whose sysfs directories are located under > /sys/devices/system/cpu/. A side effect of this is that, after the driver has > been bound to those devices, the kernel adds DRIVER=processor to ENV for CPU > uevents and they don't match the default rule for autoloading modules matching > MODALIAS: > > DRIVER!="?*", ENV{MODALIAS}=="?*", IMPORT{builtin}="kmod load $env{MODALIAS}" > > any more. However, there are some modules whose module aliases match specific > CPU features through the modalias string and those modules should be loaded > automatically if a compatible CPU is present. Yet, with the processor driver > bound to the CPU devices the above rule is not sufficient for that, so we need > a new default udev rule allowing those modules to be autoloaded even if the > CPU devices have drivers.
