Hi all, on Supermicro PDMSL-LN2+ boards there is a w83793 chip which seems to work fine, however, it seems we are hitting quite a few error messages and I don't know how to get rid off them cleanly typical messages are: [1953397.341265] w83793 0-002f: set bank to 2 failed, fall back to bank 0, read reg 0x215 error [1975470.881264] w83793 0-002f: set bank to 2 failed, fall back to bank 0, read reg 0x210 error [1996226.542514] w83793 0-002f: set bank to 0 failed, fall back to bank 2, read reg 0x8c error [2007778.861264] w83793 0-002f: set bank to 0 failed, fall back to bank 2, read reg 0x88 error [2030598.800018] w83793 0-002f: set bank to 0 failed, fall back to bank 2, read reg 0x78 error [2047548.600033] w83793 0-002f: set bank to 0 failed, fall back to bank 2, read reg 0x78 error [2061616.870018] i801_smbus 0000:00:1f.3: Transaction timeout [2061616.890025] i801_smbus 0000:00:1f.3: Failed terminating the transaction [2061616.890233] w83793 0-002f: set bank to 0 failed, fall back to bank 2, read reg 0xb2 error [2061616.890600] i801_smbus 0000:00:1f.3: SMBus is busy, can't use it!

System is running pretty recent 2.6.27 kernel and lm-sensors 3.0.2. Any hint how i can get rid off these? Cheers and thanks a lot in advance Carsten
