Generally spoken, the lm_sensors package works very good for me. But one
day it happened that after high load the application (wmlm) didn't show
any correct numbers or voltages and the computer refused to reboot until
power was switched off and on again. Later when grepping through the
syslog I found following message where I'm not sure it relates to it but
it might be:
Jan 24 14:13:43 localhost kernel: i2c-amd756.o: SMBus collision!
In the sourcecode I found following:
printk("i2c-amd756.o: SMBus collision!\n");
/* TODO: Clear Collision Status with a 1 */
and
/*
Supports AMD756 and AMD766.
Note: we assume there can only be one device, with one SMBus
interface.
*/
Now my question: Can this collision really happen or was it just bad
luck? Is there any way to improve the i2c-amd756 driver since AMD
doesn't offer datasheet anymore?
Any help would be appreciated.
