After my freeze of ISA-Bus I get now: Ok, now I get: Next adapter: uni-n 0 (Keywest i2c) Do you want to scan it? (YES/no/selectively): Client found at address 0x30 Client at address 0x48 can not be probed - unload all client drivers first! Client at address 0x49 can not be probed - unload all client drivers first! Client at address 0x50 can not be probed - unload all client drivers first! Next adapter: uni-n 1 (Keywest i2c) Do you want to scan it? (YES/no/selectively): Client at address 0x48 can not be probed - unload all client drivers first! Client at address 0x49 can not be probed - unload all client drivers first! Client at address 0x50 can not be probed - unload all client drivers first! Next adapter: mac-io 0 (Keywest i2c) Do you want to scan it? (YES/no/selectively): Client at address 0x34 can not be probed - unload all client drivers first! Client at address 0x56 can not be probed - unload all client drivers first! Before lm-sensors successfully found several sensors but jammed at the ISA check... When I type sensors now I get: flex scanner jammed Thanks for hints and Feedback. Zeno
