Hi,
I have an IP35 Pro mainboard with the uGuru feature. Until recently I was
using the abituguru hwmon driver without issue. Recently (possibly since
upgrading the BIOS to 16) the driver no longer loads, citing:
abituguru3: no Abit uGuru3 found, data = 0x00, cmd = 0x55
After looking at the code in the driver, I found the force module parameter
and tried it. Sure enough, the module loaded fine:
abituguru3-isa-00e0
Adapter: ISA adapter

ATX +12V (8-pin): +12.36 V (min = +9.60 V, max = +14.40 V)

CPU: +34.0?C (high = +75.0?C, crit = +85.0?C)
System : +28.0?C (high = +55.0?C, crit = +65.0?C)
PWM : +40.0?C (high = +80.0?C, crit = +90.0?C)
PWM Phase2: +0.0?C (high = +0.0?C, crit = +255.0?C)
PWM Phase3: +0.0?C (high = +0.0?C, crit = +255.0?C)

PWM Phase5: +0.0?C (high = +0.0?C, crit = +255.0?C)
A fix that works here is to add 0x55 as an additional cmd_val check in
abituguru3_detect(), but I think we all know this function is starting to
look a bit suspicious. I've attached a patch which does this (tested as
working), but I won't be surprised if you guys don't want to apply it.
