Hello, > ali1535_smbus 0000:00:03.1: ALI1535_smb region uninitialized - upgrade > BIOS? > ali1535_smbus 0000:00:03.1: ALI1535 not detected, module not inserted. Did you try to load wrong module? (or maybe sensor-detect tried?) There was no reboot between this and next lines? > ali1563: SMBus control = 5003 > i2c_adapter i2c-0: registered as adapter #0 > ali1563_probe: Returning 0 > Pease let me know how the first 1535 got there. Please can you provide lspci -xxx and cat /proc/ioports (before and after loading the driver) ? Thanks regards Rudolf PS: I will be in Paris (from tomorrow evening) until Sunday++; But lets hope I will find some internet connection there.
