Hi Joerg: (I tried to follow-up using the gmane.org mail/news gateway... didn't seem to work.) * Joerg Sommrey <jo at sommrey.de> [2007-08-05 12:26:04 +0200]: > Hi, > > after upgrading from 2.6.21 to 2.6.22 the CPU temperatures shown by > w83781d look unreal.

Please run the following commands as root (against both kernel versions) and reply-to-all with the results: # modprobe i2c-dev # i2cdump -y 0 0x2d b 0 0x4e # i2cdump -y 0 0x48 # i2cdump -y 0 0x49 Also, can you confirm that you're using the sensors.conf from here: http://www.tyan.com/support_download_utility.aspx?model=s.s2466 Finally, can you confirm that "sensors -s" is running (without error) some time during system startup, w/ both kernel versions?
