Hello! I tried to start a new ticket with the problem described below, but i could not find the ticket in the database after the entry. So i send the content to you by email. Maybe you could help us! Thanks in advance! best regards, Claudio Klingler We use the ali15x3 driver with the lm87 and have the same effect described in Ticket #268. After a few readings, we get an smbus timeout: Is there any hope to get those driver working? Accessing the lml87 over i2c-pci-module does not work on this board. Maybe some of the information below can help you. This problem also occurs with the 2.4.25 kernel and the 2.9.1 i2c-driver with lm-sensors 2.9.1. --------- i2c_adapter i2c-0: Transaction (pre): STS=04, CNT=20, CMD=38, ADD=59, DAT0=7f, DAT1=14 i2c_adapter i2c-0: Transaction (post): STS=14, CNT=20, CMD=38, ADD=59, DAT0=00, DAT1=14 i2c_adapter i2c-0: Transaction (pre): STS=04, CNT=20, CMD=13, ADD=59, DAT0=00, DAT1=14 i2c_adapter i2c-0: Transaction (post): STS=14, CNT=20, CMD=13, ADD=59, DAT0=46, DAT1=14 i2c_adapter i2c-0: Transaction (pre): STS=04, CNT=20, CMD=17, ADD=59, DAT0=46, DAT1=14 i2c_adapter i2c-0: SMBus Timeout! i2c_adapter i2c-0: Transaction (post): STS=04, CNT=20, CMD=17, ADD=59, DAT0=46, DAT1=14 i2c_adapter i2c-0: Transaction (pre): STS=04, CNT=20, CMD=14, ADD=59, DAT0=46, DAT1=14 i2c_adapter i2c-0: SMBus Timeout! i2c_adapter i2c-0: Transaction (post): STS=04, CNT=20, CMD=14, ADD=59, DAT0=46, DAT1=14 i2c_adapter i2c-0: Transaction (pre): STS=04, CNT=20, CMD=18, ADD=59, DAT0=46, DAT1=14 --------- Here is the output of lspci and lsmod after driver is loaded: ------ Module Size Used by eeprom 6008 0 lm87 18996 0 i2c_sensor 3456 2 eeprom,lm87 i2c_isa 1600 0 i2c_ali15x3 7460 0 parport_pc 24836 0 parport 31432 1 parport_pc rtc 9528 0 rd 4832 1 ------ 00:00.0 Host bridge: Acer Laboratories Inc.
