Some further information which upon some research, may be useful: Kernel is 3.11.2 (But misbehavior first seen with 3.11.0) $ cat /sys/devices/system/cpu/modalias x86cpu:vendor:0000:family:0006:model:0025:feature:,0000,0001,0002,0003,0004,0005,0006,0007,0008,0009,000B,000C,000D,000E,000F,0010,0011,0013,0015,0016,0017,0018,0019,001A,001B,001C,001D,001F,002B,0034,003B,003D,0068,006B,006C,006D,006F,0070,0072,0074,0075,0076,0078,007C,0080,0082,0083,0084,0085,0087,0088,0089,008D,008E,008F,0091,0093,0094,0097,00C0,00E0,00E1,00E7,0100,0101,0102,0103,0104 $ modinfo coretemp filename: /lib/modules/3.11.2/kernel/drivers/hwmon/coretemp.ko license: GPL description: Intel Core temperature monitor author: Rudolf Marek <r.ma...@assembler.cz> srcversion: 31B63A96FD9FD13CDDBDF32 alias: x86cpu:vendor:0000:family:*:model:*:feature:*00E7* depends: intree: Y vermagic: 3.11.2 SMP mod_unload modversions parm: tjmax:TjMax value in degrees Celsius (int) I have UDEV 175 from Ubuntu 12.04. The module alias seems to match that in cat /sys/devices/system/cpu/modalias, so udev should be able to probe for and load coretemp.ko, but that is not happening, which is strange to me. I also note that microcode.ko, which is handled by the same mechanism for auto-loading based on CPUID, is no longer auto-loaded in kernel 3.11.x. I have added Thomas Renninger and Greg Kroah-Hartman to the thread CC. Thanks.
