[Bug 354816] Re: system freeze when using network with linux-rt on smp amd64 machines

[Rafael Gálvez-Cañero]

I downloaded pkg sources for linux-2.6.28-11.42 and looked around rules,
control and other debian files. A bit overwhelming, I think my first
package should be something little and with no possible side-effects...
And kernel is not any of that. Sorry. With more time in my hands, maybe
I could try.

I can upload somewhere the binary build and you can trust me I have not
applied vile patches... Or I can tell you what I've done (nothing weird,
really simple).

It is easy: grab a vanilla 2.6.29 (last at post time is 2.6.29.4 [1]),
apply the corresponding rt patch (2.6.29.4-rt16 [2]), copy the
configuration from the last 2.6.28 ubuntu kernel over the new one,
enable full rt-preemt and set to 1000Hz the config and make-kpkg. I also
used the PPA from Michael Marley to get updated nvidia drivers [3]. You
can look for outdated instructions on build an rt kernel for ubuntu here
[4] to get inspiration over the config step.

Sorry to not be more helpfull. I can test and run anything you want in
my computer, but I can not try packaging a kernel right now.

PD: At this ancient bug they are doing similar things. Look for comments from Realtime Dutchman and vivichrist.
