Khali: Is i2c-dev safe (ruin-proof) for people > with IBM laptops? Or would that check need to be built in to this? It isn't safe. Single quick writes to addresses 0x54-0x57 are likely to kill IBM laptops (it actually depends on what command is ran next). That said, at the moment i2c-piix4 won't load on supposedly vulnerable systems, so it shouldn't happen. I have plans to replace quick writes (for detection) by byte reads for this address range in Linux 2.6's i2c_detect/i2c_probe, just like I did in i2cdetect and sensors-detect already, but it doesn't address the i2c-dev issue. Maybe we can hack i2c-dev to prohibit quick writes to the eeprom range entirely? That way all user-space tools would automatically be safe. -- Jean Delvare http://khali.linux-fr.org/
