Subject: [lm-sensors] ITE IT8721F, IT8758E it87 standalone driver report
Date: Wed, 06 Apr 2011 20:17:22 +0000	[thread overview]
Message-ID: <2610648201.20110407001722@mail.ru> (raw)

Hello, Lm-sensors.

Sending  report  about using standalone driver for IT8721F, IT8758E at
Ubuntu 9.10 with kernel 2.6.31.12 with motherboard Foxconn D42S.

I  was  unable  to build just driver from sources, so i put it into my
kernel sources: replace original drivers/hwmon/it87.c with new one.
Next i compile and install kernel and found a problem:
> # modprobe it87
> FATAL: Error inserting it87 (/lib/modules/***/drivers/hwmon/it87.ko): Device or resource busy
But found a solution:
> Basically, you need to add a new kernel line in your menu.lst to fix
> this behavior.
> acpi_enforce_resources=lax
And it was good for me.
Now the sensors give me correct output, but without names (temp1, fan1
and  so  on), so i had to edit /etc/sensors.conf and now the output is
correct for me (temp and fans)
