Hi, after going back from kernel 2.6.8 to 2.4.27 sensors-detect produces the following output in my syslog: Feb 2 01:22:09 vernon kernel: ALi Corporation M7101 PMU: ALI15X3_smb region uninitialized - upgrade BIOS or use force_addr=0xaddr Feb 2 01:22:09 vernon kernel: ALi Corporation M7101 PMU: ALI15X3 not detected, module not inserted. I had no pronlems running kernel 2.6.8 with modules i2c-ali15x3 and lm75 on the same machine (i568, 233 MMX). I have no idea how to figure out which address range could be free. Thanks Marcus
