**** WARNING: IBM Thinkpad users should not install I2C/Lm_sensors! **** |
|---|
| 3 |

| 4 |
There have been some reports that the eeprom and/or firmware of IBM |
|---|
| 5 |
Thinkpads have been corrupted after installing I2C/Lm_sensors. It's not |
|---|
| 6 |
clear why and what specific action (most likely scanning/probing for chips) |
|---|
| 7 |
causes the Thinkpad to corrupt it's eeprom. Unless you know otherwise, we |
|---|
| 8 |
suggest that users avoid installing I2C/Lm_sensors support on IBM Thinkpads |
|---|
| 9 |
until it becomes known what exactly is causing the corruption. |
|---|
| 10 |
|
|---|
| 11 |
Though you may disagree about whose fault this is, fact is that seemingly |
|---|
| 12 |
the Thinkpad can become corrupted even when only reading information from |
|---|
| 13 |
the i2c/SMBus. Be assured that we never, ever write any information to |
|---|
| 14 |
the bus while scanning(*), and that no halfway sane client implementation |
|---|
| 15 |
should change its internal state, not to mention overwrite system-critical |
|---|
| 16 |
information. |

(*) Actually, we do write some information to the bus, but only as specified |
|---|
| 23 |
in the i2c/SMBus protocol to select a certain chip address and to |
|---|
| 24 |
start/stop i2c transactions. |
