Hi,
I do use Knoppmyth R5A15.1 and I really enjoy it, but my happiness turned to nightmare since I bought a Ovislink EVO54PCI. This toy is a Wifi PCI Card based on the famous Ralink Chipset, the -only ?-one well supported on linux with native drivers, that means without ndiswrapper crap. The card works very well under Mandriva 2005LE, so there shouldnt have any harware problems. On my Knoppmyth box the systems freezes each time I connect to the net, between 3 and 5' after the connection is up. I can only use Alt+PrintScreen+B to do a reset, nothing else doesnt work. I use the Serial Monkeys drivers: http://rt2x00.serialmonkey.com/wiki/index.php/Downloads, I tried both the daily CVS driver and the last 1.1.0-b2 driver, without any success. I even tried to use the proprietary drivers from Ralink, too bad too. I asked the coder Mark Wallis, who seemed to think the trouble occurs with SMP or 4k Stack Kernel. The Knoppmyth kernel is a SMP kernel, that is that uname -a seems to say ; I dont know what to do, I would really like to use Knoppmyth to finish my box instead of Mandriva.
Does anybody use Ralink chipset with better luck, or could someone help me ?? I am even ready to compile another kernel, although I'm not a linux guru, but I'm not sure it is the solution...Help please !!!

You can recompile the kernel w/o SMP. As for 4K stack it is disabled.

Thanks for the quick answer.
I have never recompiled any kernel but why not, there are many useful howtos for this ;
I was not sure it was a good idea because I tried yesterday a "make menuconfig" in /usr/src/linux and the 4k stack was disabled, so I was wondering if it was necessay to disable something which was already disabled. I'm gonna try to recompile...

sounds like a pretty bad bug if it doesn't work with smp. Seems like the developers would work that one out in short order unless the codebase is just in too much disarray. I can understand not worrying about it in the past, cause servers don't usually need wireless, but now that the pIV uses smp for hyperthreading and dual core's will make their way to the desktop in short order that is a bug I would be looking into.

Hi, I still can't solve this trouble. I just can't recompile the Knoppmyth kernel properly without losing modules and so on. With the kernel-source (2.6.11.7-chw4 for the R15A15.1 release), or with a new kernel such as 2.6.12, I got a working kernel, without SMP, and my Ralink-based Wifi card works flawlessly, but I haven't got ivtv or nvidia anymore. I did use this tuto (sorry it's french) http://trustonme.net/didactels/285.html which is quite good in my opinion, but as a result the distrib is quite unusuable.
Could anybody help me with a tuto about the kernel recompilation using Knoppmyth or a Debian ? Google doesnt really help.
Thanks

well the ivtv source is in /usr/src, and the install-nvidia???? script will reinstall the nvidia drivers, if those are the only two things you are worrying about I would just go ahead and compile those modules and be done, as long as you don't need one of the many other patches cesman includes in the kernel.

Perhaps a search on this forum for "kernel upgrade"?

But you mention that when you upgraded the kernel you lost modules. That probably means that you forgot to build and install the new modules. I usually do:

cp /proc/config.gz /usr/src/linux
cd /usr/src/linux
gunzip config.gz
mv config .config
make oldconfig
make install
make modules modules_install
