My 64studio unfortunately got one problem; the network goes down after a while (varying from min. to hours). This is annoying as it is placed in my caller and I’m accessing it by nx (a vnc variant). After hour of trying different things, browsing different Linux resources etc., I might have found the answer; it’s apparently a kernel problem solved in 2.6.23? Is it possible to upgrade the 2.6.21-1-multimedia-amd64 kernel to 2.6.23 witout damaging any of the specialties on 64studio – realtime features etc.? https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/87078 quote-------- Dimitar Mihailov wrote on 2007-10-11: Kernel 2.6.23 is out! And guess what is in the changelog! Change INT0 trigger mode from edge-sense mode to level-sense mode, in order to fix the following timeout error: 'NETDEV WATCHDOG: eth0: transmit timed out'. Coool! :) ----unquote regards ole pedersn

Finally I managed to patch,

Finally I managed to patch, compile and install the 2.6.24.4-rt4 kernel and it is working fine, except that the original network problem persists. I am starting to suspect a HW problem.

Just an update to report the final solution. It turned out to be a HW problem, I upgraded the system to Intel Dual Core Quad/MSI P35 NEO, and this combination has no IP connectivity problems. The faulty combination is: Mother board: ASRock K8SLI, CPU: AMD Sempron 3400 64bit. I suspect the motherboard to be the faulty part.

picothinker - Sorry for the late response. I’m afraid I can’t help. I just followed the install instruction on the NX site, and it work without any problems. These: http://www.nomachine.com/download-package.php?Prod_Id=2 Regards /ole

Ole, can you outline the NX process for 64Studio? I got it running on a Fedora machine, but overall had some troubles getting it running on others. It is a great way to operate remotely, and uses the least resources of anything I have tried.

kernel 2.6.24.3 in use

I recently patched the kernel version 2.6.24.3 with a matching Molnars RT patch. For compiling I copied 64Studio /boot/config-2.6.21-multimedia file as a new .config in the kernel source directory. Compiling went by without errors and I was able to make a .deb -package with make-kpkg, the Debian way of compiling kernels. The new kernel is now Linux 64studio 2.6.24.3-rt3 and works fine - it's running right now..

Kernel change...

Yes, there is a problem. You could try to compile your own realtime kernel, but is is not as easy as that sounds... Search for walk troughs regarding building your own realtime kernel (You'll have to patch it with Ingo's RT patch, and it might be a while for a stable patch to emerge) Good luck, and let us know! Cheers,

Kernel change

Thanks I’ve been googling and found Ketchup – would it work/make is easier? Regards Ole Pedersen
