[lm-sensors] Problems reloading sis5595 since kernel upgrade to

[Pinkel]

Hey,

Yesterday, I upgraded my kernel on my sis5595 "PC" to 2.6.22.9, while 
trying to converting the sis5595 device driver to support individual 
alarm files.
The first thing I noticed, is that when I loaded my patched version, 
nothing happened. I couldn't find any file in sysfs and sensors said 'No 
sensors were found.'.
First, I thought I messed things up, which wouldn't be very surprising.
However, after rebooting, I noticed that it also seem to happen in the 
original sis5595:

1. I boot my pc. I run sensors (vanilla config) and....
--
[ivo@localhost ~]$ sensors
sis5595-isa-0290
Adapter: ISA adapter
VCore 1:   +2.96 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
VCore 2:   +3.41 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
+3.3V:     +2.75 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
+5V:       +3.44 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
+12V:     +14.71 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
fan1:        0 RPM  (min =   -1 RPM, div = 2)          ALARM
fan2:        0 RPM  (min =   -1 RPM, div = 2)          ALARM
alarms:   Board temperature input (usually LM75 chips) ALARM

2. I reload the module
--
[ivo@localhost ~]$ sudo /sbin/rmmod sis5595
[ivo@localhost ~]$ sudo /sbin/modprobe sis5595

3. Then I run sensors
[ivo@localhost ~]$ sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

[ivo@localhost ~]$ sudo /sbin/lsmod | grep sis5595
sis5595                17993  0
i2c_sis5595            11077  0
hwmon                   7365  1 sis5595
i2c_isa                 8257  1 sis5595
i2c_core               27841  4 sis5595,i2c_sis630,i2c_sis5595,i2c_isa

[root@localhost sis]# uname -r
2.6.22.9-61.fc6

Any idea what happens here? I'm clueless. Can't find anything in any log 
file either.
The only thing that shows up after playing around with loading and 
unloading modules, and running sensors-detect is
--
Oct  8 04:25:20 localhost kernel: spurious 8259A interrupt: IRQ7.

But I suppose that's unrelated?

Try unloading i2c-sis5595 before you reload sis5595. The i2c-sis5595
driver refuses to share the PCI device with other drivers until 2.6.23.
See:
