hi,
i had a hard time yesterday getting tinycore 4.x work on Neoware BA-EON4300S x86 thin-clients.

read post at
http://article.gmane.org/gmane.linux.kernel.cpufreq/7986

Until that problem is resolved upstream i would recommend that this module is being blacklisted in Tinycore, as there are still lots of Neoware ora VÍA C3/nehemiah "out in the wild".

regards
roland

We can't selectively blacklist, and I assume it is still useful for later Via cpus.

Noting here too that the fix was "longhaul.disable=1", disabling the module.
The only barriers that can stop you are the ones you create yourself.

I don't think this is limited to TC4X.

I have a VIA C3 nehemiah cpu on my media server motherboard running TC3 and this module also causes my machine to hang.

Having certain modules blacklisted by default is a door you not want to open, because once you do,
where do you draw the line? It starts with module A. Then you add B, and C, and D, ......  Next thing
you know, members start posting that they want or need module C, which is now blacklisted by
default. One of Tinycores features is to be bootable out of the box with little to no effort by the majority
of users. Should an included module ever start causing problems for the majority of users, I suspect
that rather than be blacklisted by default, it would be moved to a tcz as an optional module.
Blacklisting is the responsibility of the end user, as it should be.

but why does TC3 work without problems? I assume the module isn`t being loaded there by default, so the question is what makes it load by default on TC4.

It is a different kernel.

cpufreq kernel moduls are not included in TC 3.x base and optionals via .tct while TC 4.x base comes with these modules including longhaul.

if tinycore means "Tiny Core", why is  addon-stuff included, which keeps users from running it?

Ok, just kidding;)

But AFAIK,Tinycore is often running on small and especially old machines and at least i have seen lot`s of reports of issues with longhaul module, so i`m curious if it adds real benefit or keeps users from using tinycore. The problem is: if tinycore does not work because of such module, it`s difficult to find out the reason and it maybe even more difficult to fix it, because there is no easy way to "adjust" the base system. (i.e. remove the module etc)

I do not know whether the longhaul modul is broken or the chipset is buggy. To have CPU frequency scaling by default activated is a good idea. However it is not essential to have. One possible solution to remove just longhaul from base and move it to a .tcz.

Is the situation the same with 4.4rc? If so, better to mention your issue at

Hi,

How can I disable this module when booting from the CD?

I cannot complete USB install because the machine locks before the install process completes.

Thanks.

Hi b1ackmai1er
Did you try the boot code suggested by curaga in reply #1?

yes, thanks.

I typed longhaul.disable=1 at the command line but it did not work but it looks like I need to type "tc longhaul.disable=1" at the boot command line. Thanks.

Now I want to set up my system to usb boot using tc-install. It has the option to enter command line options as well. Do I use the same  "tc longhaul.disable=1" at this prompt? or do i skip the tc or do I need to use blacklist longhaul?

Thanks

Hi b1ackmai1er
Skip the tc, it is only used when manually adding something at the boot prompt.
