Hi sorry for sending this to the lm_sensors address, but I did not find any separate i2c address one the web. I checked out the most recent source code from CVS and tried to compile the i2c package first, the compilation stopped with the message below gcc -D__SMP__ -I/lib/modules/2.4.19-SMP/build/include -nostdinc -I /opt/gcc33/lib64/gcc-lib/x86_64-suse-linux/3.3/include -Wall -O2 -DLM_SENSORS -D__KERNEL__ -DMODULE -fomit-frame-pointer -DEXPORT_SYMTAB -fno-strict-aliasing -fno-common -fomit-frame-pointer -mno-red-zone -mcmodel=kernel -fno-reorder-blocks -finline-limit=2000 -fno-strength-reduce -c kernel/i2c-algo-biths.c -o kernel/i2c-algo-biths.o /lib/modules/2.4.19-SMP/build/include/linux/module.h:300: warning: `__module_kernel_version' defined but not used kernel/i2c-algo-biths.c:771: warning: `__module_license' defined but not used /tmp/cckgMevc.s: Assembler messages: /tmp/cckgMevc.s:1387: Error: Incorrect register `%rdx' used with `l' suffix make: *** [kernel/i2c-algo-biths.o] Error 1 I run Suse Linux Enterprise Server at the moment with Dual Opteron in 64 Bit mode with SLES 2.4.19 kernel (according to suse with the latest relevant Opteron patches. The error occurs both with gcc-3.2.2 und gcc-3.3 Maybe this is interesting for you ..
