**** WARNING: IBM Thinkpad users should not install I2C/Lm_sensors! ****
|
|
|
|
There have been some reports that the eeprom and/or firmware of IBM
|
|
Thinkpads have been corrupted after installing I2C/Lm_sensors. It's not
|
|
clear why and what specific action (most likely scanning/probing for chips)
|
|
causes the Thinkpad to corrupt it's eeprom. Unless you know otherwise, we
|
|
suggest that users avoid installing I2C/Lm_sensors support on IBM Thinkpads
|
|
until it becomes known what exactly is causing the corruption.
|
|
|
|
Though you may disagree about whose fault this is, fact is that seemingly
|
|
the Thinkpad can become corrupted even when only reading information from
|
|
the i2c/SMBus. Be assured that we never, ever write any information to
|
|
the bus while scanning(*), and that no halfway sane client implementation
|
|
should change its internal state, not to mention overwrite system-critical
|
|
information.
|
|
|
|
For more information, see:

|
|
|
|
(*) Actually, we do write some information to the bus, but only as specified
|
|
in the i2c/SMBus protocol to select a certain chip address and to
|
|
start/stop i2c transactions.
