Hi Mark,
just to eliminate as many impacts as possible, I did:
- reinstall the unmodified sensors.conf from Tyan's support page
- power off before rebooting
A call to "sensors -s" is done without errors in all cases.
The module parameters I use currently with both kernels:
options w83781d force_w83782d=0,0x2d force_subclients=0,0x2d,0x48,0x49
options w83627hf force_addr=0x0c00
When I first realized the problem, I didn't use w83627hf yet. Results
are the same when w83781d is used as driver for w83627hf.
Parameters in that case just from Tyan:
options w83781d force_w83782d=0,0x2d force_subclients=0,0x2d,0x48,0x49 force_w83627hf=0,0x2c force_subclients=0,0x2c,0x4a,0x4b init=0
"My" i2cdump doesn't accept an -y option, maybe a Debianism. Results
see below.
TIA
-jo
