Hi Jean I tried to install lm-sensors 2.8.0 again ( I got my computer back and running on KDE). While running sensors-detect it hung at checking for IS0... No I get the same error message again during start up as I got last time when we had to delete something from /usr/src/linux/.... I can't remember anymore what you told me exactly to do. Can you resent me that mail please. My error again is: vector 300 at pc = e238c288, lr = e238f080 msr = 9032, sp = d8667cf0 [d8667c40] dar = 24, dsisr = 40000000 current = d8666000, pid = 879, comm = modprobe mon> Then everything hangs while startup. Thanks for yor feedback. Zeno
