Description Dave Andruczyk 2003-11-26 16:35:03 UTC

build of lm-sensors package (normal unmasked version 2.7.0-r1) went without incident.  /sbin/
sensors-detect was run with the safest choices. (NO ISA probing,  use smbus instead of ISA). 
 
insertion of i2c-amd756 module went without errorNov 26 19:19:13 shrapnel i2c-core.o: i2c core 
module version 2.7.0 (20021208) 
Nov 26 19:19:13 shrapnel i2c-amd756.o version 2.7.0 (20021208) 
Nov 26 19:19:13 shrapnel i2c-amd756.o: Found AMD766 SMBus controller. 
Nov 26 19:19:13 shrapnel i2c-amd756.o: AMD766 bus detected and initialized 
 
 
insertion of w83781d module results in immediate deadlock. if sound is playing the card loops in its 
buffer forever.  no mouse, no keyboard response.  only fix was reset via reset button or power. 

Reproducible: Always
Steps to Reproduce:
1.emerge lm-sensors 
2./etc/init.d/lm-sensors start 
3. 
Actual Results:  
upon insertion of the w83781d module by lm-sensors  script system locks hard. 

Expected Results:  
module should have inserted without error or hardlock. (error is much preferred to hard freeze)  About 
6 months back this DID work.
