Upon updating to the latest kernel (2.6.16-1.2122_FC5) & rebooting I find that I no longer have lmsensors. /var/log/messages gives this in the suspect area: ========== . . . May 22 11:42:42 localhost kernel: i2c_adapter i2c-0: SMBus Quick command not supported, can't probe for chips May 22 11:42:42 localhost kernel: i2c_adapter i2c-1: SMBus Quick command not supported, can't probe for chips May 22 11:42:42 localhost kernel: i2c_adapter i2c-2: SMBus Quick command not supported, can't probe for chips . . . ========= Responses I got from the Fedora mail-list seemed to indicate that this is specific to Asus M/B's. Mine is an Asus P4B533. I have been using lmsensors on this system for several years thru many Fedora kernels. The previous kernel (kernel-2.6.16-1.2111_FC5) & kernels prior work fine. I get the impression that since a small population is having the issue no effort will be made on the kernel side. Any advice is welcome.
