From: Guillaume Chazarain <guichaz at yahoo.fr> The commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=32c82a934759b2c9939c9e25865c2d7d1204b9e8 broke lm90 for my (Asus V6VA) laptop. Before 2.6.23-rc1 and with the following patch, I get: [g ~]$ sensors max6657-i2c-0-4c Adapter: SMBus I801 adapter at 0400 M/B Temp: +64??C (low = +0??C, high = +127??C) CPU Temp: +78.9??C (low = +73.2??C, high = +88.2??C) M/B Crit: +105??C (hyst = +95??C) CPU Crit: +105??C (hyst = +95??C) Which regressed into: [g ~]$ sensors No sensors found! Make sure you loaded all the kernel drivers you need. Try sensors-detect to find out which these are. zsh: 2701 exit 1 sensors and dmesg contains: i2c-adapter i2c-0: Unsupported chip (man_id=0x4D, chip_id=0x4D). It seems to be a typo, as address 0X4F is mentionned nowhere else in the file, and my chip is actually at 0x4C.
