** OFFICIAL ** Intel DX38BT & DX48BT2 BoneTrail Thread

And of course I totally forgot to upload it so I'll do that now and post the link in about 30 minutes.

OK, posted at http://www.peakin.com/x38/asc76xx.zip
Unzip it in an empty directory and read README and INSTALL

Thank you very much!

At first I just saw this error in dmesg:

[ 4558.898570] i2c-adapter i2c-1: asc76xx not found at 1,0x2e.

The chip seems to be an aSC7621a (with an a on the end), i.e. COMPANY=0x61 and VERSTEP=0x6d. I was
not able to make your kernel module work unless I patched it like this. The kernel is linux version 2.6.24.

Then after

modprobe asc76xx
dmesg

I see the following (with debugging messages turned on):

Which looks ok. Then

sensors

gives the following

I only have a fan connected to the MCH fan header on the motherboard so I would have
expected to see one non-zero fan speed -- but actually I don't see it in
the bios (v1397) either.

Does that look ok to you? Do you know how to interpret the figures -- i.e. which fans and temps are which? The CPU is a QX9650.
