longhaul is loaded despite being reported broken

[reto]

Problem is occurring since kernel .31.2 on Karmic Koala
In kernel .28.xx Longhaul is also reported as "is currently broken in this configuration" on startup, but it is not loaded. I could therefore use e_powersaver which works good. This is not possible anymore since Longhaul is loaded anyway. It seems to be compiled into the kernel so I cannot disable it. Wouldn't it be better to have it as a module?

I'm using a HP mini 2133 with a VIA C7-m CPU.

I hope that is enough information. My first bug report :)

Cheers

I would like to request loading it as a module. According to VIA: http://www.viaarena.com/displaydownload.aspx?PageID=1&DSCat=32&DCatType=3
"The Power Saver feature is considered experimental at this time and users are advised to visit VIA Arena regularly for the latest update.

An IDE lockup issue occurs on some VIA EPIA Mini-ITX mainboards when the Power Saver feature is enabled. A patch to resolve this issue is available for Fedora Core 3.0/4.0/.50 in the drivers section."

VIA has a bios beta update that might address this issue: http://www.viaarena.com/displaydownload.aspx?PageID=1&DSCat=155&DCatType=3
Since this bios is listed as a beta, users shouldn't be expected to use it.

Confirmed! Please remove longhaul support from in-build kernel as it makes my via epia to freeze at random time.

Hello,
I also have an HP Mini 2133 and based on some benchmarks I made using the distributed.net client it runs at halfspeed compared to the Windows XP version running on the same hardware.
It seems that what ever cpufreq reports the Via C7-M CPU always runs at 800 MHz (instead of 1600 MHz).

I tried to follow these guidelines:
https://wiki.ubuntu.com/LaptopTestingTeam/HP2133/CPUScalingFix
Since I did not find the menu.lst file I edited the grub.cfg this changed nothing.

There is also this thread "e_powersaver driver considered DANGEROUS (was Re: Linux 2.6.30-rc8 [also: VIA Support])"

It is still there. Please fix it

reto, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>
