Bug Description

SRU justification:

Impact: There are a certain variation in the string provided by some mainbord
        manufactures in the name they provide in the DMI information between
        BIOS releases. The abituguru3 is a sensor driver that matched very
        strictly to certain names and it was found this causes boards which
        run well before, not to be detected after switching to DMI matching.
Fix: backported patch from upstream which loosens the checking to match
     partial strings instread of the long versions.

Testcase: Driver would not load with certain boards. Verified to be working
          after applying the patch.

FATAL: Error inserting abituguru3 (/lib/modules/2.6.27-7-generic/kernel/drivers/hwmon/abituguru3.ko): No such device

On Ubuntu 8.04 (hardy), the abituguru3 module loaded properly, making the ABIT uguru sensors for my ABIT IP35 Pro motherboard available. On Ubuntu 8.10 (intrepid), the abituguru3 module fails to load as shown.

Forcing the module appears to work.

Note: I searched the internet for information on this issue, and did not find much. I did find a bug report on Mandriva that appeared similar:

Information was sketchy, but perhaps it is already in the pipeline to be fixed in an upcoming patch.

Hi Russ,

After you 'sudo modprobe abituguru3' is there any additional information in your dmesg output? Care to attach it here?

Changed in linux:
status: New → Incomplete

Here's the dmesg output of a modprobe abituguru3 without force:

[173460.771302] abituguru3: no Abit uGuru3 found, data = 0x00, cmd = 0xFF

And here is the dmesg output with the force option:

[173531.848187] abituguru3: no Abit uGuru3 found, data = 0x00, cmd = 0xFF
[173531.848193] abituguru3: Assuming Abit uGuru3 is present because of "force" parameter
[173531.892560] abituguru3: found Abit uGuru3, motherboard ID: 001A


I did some searching at kernel.org, and found this:


So, it looks like it's fixed in 2.6.27.

The patch mentioned in the upstream report is already available in Intrepid which has a 2.6.27 based kernel.

    abituguru3: prefer DMI probing to manual probing

    Previously the driver was only using DMI to prevent smbus probing on

    non-Abit motherboards. However, since the manual probing method is

    brittle and prone to failure on some Abit motherboards (esp. the Abit

    IP35 Pro) it is better to use DMI to also read the board name and then

    decide whether or not to probe the bus.

    At the moment, we do not have a list of valid DMI name strings to use

    for existing and supported motherboards. This patch only implements DMI

    probing for the IP35 Pro. For motherboards that can not yet use DMI

    probing, a warning will be printed to the kernel log asking those users

    to email me their dmidecode output.

    The existing manual probing mechanism will be used if CONFIG_DMI is not

    enabled, if DMI probing fails (for DMI-unsupported motherboards), or if

    DMI probing fails and the "force" option is set (for DMI-supported

    motherboards). Ideally in the longer term this manual probing method

    would be removed.

    This patch should be safe to apply as it does not change the probing

    behaviour for most of the supported motherboards, just the IP35 Pro,

    which already has regressions filed against it in 2.6.26.

Hi Russ,

could you do another check against the latest kernel and if it still does not work supply the output of "sudo dmidecode". Thanks.

Hi Stefan,

No luck. In fact, now forcing doesn't seem to work, either (invalid module format???). Here's the info:

Oh, and the modprobe (without force) generates the following output in dmesg:

Thanks again,


I see the Product Name, "IP35 PRO(P35+ICH9R)", doesn't match any of the strings defined in the abituguru3_motherboards table. It's close to "IP35 Pro(Intel P35-ICH9R)", but close doesn't count in strcmp()!

Interestingly, the name I get is the same as the product name sent in this post to the lm-sensors list in May:


Someone else must have sent in the the one in the table -- nice of ABIT to change it!


Hi Russ,

nope, the most would be partial matches. But that won't work if some vendor
decides to drop words in the middle and - does sound too inferior. ;-)
Alright, since your board id is still 1a, so I just made a new clone of the
other table for IP35. I got a test kernel uploaded to my PPA. I had hoped this
would be based on the latest -proposed kernel but those versions are moving
fast at the moment. But for a quick test it should be ok to not have all the
depending packages. Could you try that kernel and tell me whether this works as


Hi Stefan,
  Sorry for the delay, the holidays got in the way, I haven't had a chance. I'll try to get a test in this week.

Hi Russ,

sorry I got buried in other stuff. :( After all I think it is simpler to get you a kernel based on 2.6.27-11 than to try get the PPA build right. I uploaded those kernels here: http://people.ubuntu.com/~smb/bug298798/ I actually found a patch from upstream that should fix this. I that works for you, I'll get those into Intrepid and Jaunty. Thanks.

Hi Stefan,

Somehow, I missed your last message. I was waiting for a new kernel to spring into your PPA! Anyway, I installed the 2.6.27-11 kernel you linked above, and...

ramirand@zygoma:~$ lsmod | grep -i uguru
ramirand@zygoma:~$ sudo modprobe abituguru3
[sudo] password for ramirand:
ramirand@zygoma:~$ lsmod | grep -i uguru
abituguru3 36496 0
ramirand@zygoma:~$ dmesg | grep -i uguru
[ 108.642215] abituguru3: found Abit uGuru3, motherboard ID: 001A


Thanks for your work on this, sorry the communication was so sporadic!

This bug is still present with my motherboard, probably because it is the "XE" version (Abit IP35 Pro XE) with the product name string: "IP35 Pro XE(Intel P35-ICH9R)".

I have the same symptoms as Russ Miranda have reported:

Should I open a new bug report since I'm using another version of the IP35 motherboard?

Rune K. Svendsen (runeks) wrote :

Here's the complete output of dmidecode.

Definitively open a new bug if you are sure this board really has the right
chipset. Compared to Russ, your forced probe fails, which sounds like there is
more difference than just the right string.

Rune K. Svendsen (runeks) wrote :

Per the instructions of the maintainer of abituguru3, Alistair John Strachan, I tried issuing the following command using abituguru3's own 'force' parameter like so:

modprobe abituguru3 force=1

and this works. Alistair is in the process of fixing the issue, I just tried a patched kernel of his right now which, ufortunately, didn't work (could be something on my part though, we'll see). But it's being worked on!

Stefan Bader (smb) wrote :

Oops, sorry, did not read careful enough and somehow imagined you had done the
force=1. But anyway, it is better to have that as a separate bug since the
problem was solved for the other board and this is sort of a new problem,
though maybe with a similar resolution. But the more specific a single bug is,
the better it is workable.

Rune K. Svendsen (runeks) wrote :

Alistair John Strachan's most recent patch to abituguru3 fixes the issue for me. So I don't consider it a bug any more, though it might not make it into 2.6.31. But I don't think there's a reason to create a new bug report for it. I see that it would be best to isolate each bug to its own bug report so I will leave this message as my last. But hopefully my comments can help other Linux users with the Abit IP35 Pro XE motherboard to know that they have to pass the force=1 parameter to the abituguru3 modprobe to get it working.
