Make sure radeon is loaded before lm63 since the radeon i2c buses don't exist until radeon is loaded. Try unloading lm63 if it's already loaded and then reloading it after radeon has loaded:
modprobe -r lm63
modprobe lm63

I've tried that, again, to no avail.Originally Posted by agd5f
I noticed something on dmesg:
i2c-core shows up on the boot process, but it is not showing on lsmod:Code:$ dmesg | egrep i2c [ 1.347993] i2c-core: driver [adp5520] using legacy suspend method [ 1.347996] i2c-core: driver [adp5520] using legacy resume method [ 9.066050] i2c /dev entries driver
Thanks for helping.Code:lsmod | egrep i2c* i2c_dev 13399 0 i2c_algo_bit 13436 1 radeon i2c_viapro 13153 0
I'll ask on the mailing lists.

Hello. My video card is 4870x2 and I'm using open source radeon driver (xf86-video-ati). I can only get temperature of gpu1 but not gpu0.
These are what I set in kernel:

As you can see there is only temperature of gpu1. Temperature of gpu0 should be 85-90°C (Yes I know it's too high due to my old system case :/ ). Sometimes it rises above 90°C and I have to manually turn power_profile to "high" (which was set to "auto") to speed up gpu fan to cool down a bit. That's why I need gpu0's temperature rather than gpu1's. Is there anyway to get gpu0's temperature with open source radeon driver?Code:$ uname -a Linux localhost 3.4.2-gentoo #2 SMP Wed Jun 13 20:05:53 CST 2012 x86_64 Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz GenuineIntel GNU/Linux

Is the driver loaded on both GPUs? Check your dmesg output. Probably best to file a bug.

These are some messages related to drm/i2c from dmesg output:
