Same here on Acer Travelmate 8100. It seems like this module get loaded on all kind of Acer hardware which has nothing to do with Acer Aspire One. Either it should not have been loaded here, or the message should be toned down a bit.

[Niels Kristian Bech Jensen (nkbjensen)]

I see the same on an Acer Extensa 5220:

acerhdf: unknown (unsupported) BIOS version Acer /Extensa 5220 /V1.35 , please report, aborting!

I agree the module should test for the Acer Aspire One and only load on such hardware.

[zoran (zokiskopje)]

I have the same warning

[Kim d'Audretsch (kimda)]

Same warning on the 1810T acer timeline series.

acerhdf: unknown (unsupported) BIOS version Acer/Aspire 1810T/v0.3108, please report, aborting!

[Tormod Volden (tormodvolden)]

From the module aliases in the kernel module, I think it gets loaded for all Acer/Gateway/Packard Bell machines:

MODULE_ALIAS("dmi:*:*Acer*:*:");
MODULE_ALIAS("dmi:*:*Gateway*:*:");
MODULE_ALIAS("dmi:*:*Packard Bell*:*:");

Until this is fixed upstream, I suggest just lowering the severity of the warning so that it does not show on a normal "quiet" boot. It can be tempting to rephrase it, especially the over-dramatic "aborting" part, but I think it is best to leave the text as it is upstream.

Similar error here on Acer Aspire 4710, but boots into the laptop alright. Just shows these warning signs and says something like could affect performance and then boots into Kubuntu 9.10 alpha 6 with all the latest updates.

thanks

Same warning in Karmic Koala on Acer Timeline Travelmate 8471:

[Tormod Volden (tormodvolden)]

Just to make that clear, these messages are totally harmless. (Unless you have an Acer One and want to control the fan.)

[David Racine (bass-dr)]

Same on Acer Aspire 5110, good idea to hide on quiet boot.

Beyond "totally harmless" - the fan actually seems to be functioning better, now.

Using alpha6, Same error message on Acer Aspire 5535.

dmesg output attached.

Thanks for looking into it!

[Neil Wilson (neil-aldur)]

What's worse is that if you *do* have an Acer Aspire One, this module
doesn't automatically activate the enhanced fan functionality. You
have to do it by hand!

It would be nice to add the appropriate value into the sysctl system.
If the module is active, we should at least try to use it on the right
hardware.

[Tormod Volden (tormodvolden)]

Thank you everybody, we don't need more confirmations, even if it says "please report" :)

Neil, please file the missing activation as a separate bug.

The first identified problem I'm having is that my brightness control buttons does not work. Even if I go to power management and set the brightness gives no effect. The brightness of the monitor remains in its MAX.

[Shane Lazar (drsjlazar)]

I have an Acer Aspire 3003NLMi and I get the same error in dmesg. However, in Karmic the control of the fan is problematic. Quite often the fan fails to start up and remains off even when the temperature goes up above 80 degrees C! It has not been a rare occurrence for my laptop to power off because of over heating (at 97 degrees C).

My main installation is Linux Mint 6 Fluxbox CE which is based on Intrepid... and I have no such problems with fan control there. I have started another thread but it seems this one is more active.

It is a real bummer to constantly keep an eye on CPU temps and throttle down manually when temps get too high.

[Marc Quinton (mquinton)]

I have same message : "acerhdf: unknown (unsupported) BIOS version Acer /Aspire 7720 /V1.45, please report, aborting!" ; if I can help reporting some hardware information, just contact me.

[Tormod Volden (tormodvolden)]

Actually, nobody has to report anything any longer :) The bug is confirmed and everything has been clarified, a bug fix has been proposed for karmic and upstream is aware of the problem.

Kernel 2.6.31-11.38 has not fixed the brightness bug on my Acer Aspire 5738Z laptop.

Anyone know a kernel that works? I had a 2.6.30 that worked perfect on Ubuntu 9.04, but that kernel doesnt work with 9.10.. Sound and touchpad fail to work with it. The brightness is so bright its causing major headaches :( - Thanks!
