Thanks for the info Scoop. I'll have support take a look at that (server in DC so no access). In my case there are two, eth0 being public network and eth1 being private, but if this is the same problem I should notice things fubar in that file.

Thanks!

Any ideas why this happens?
I'm also getting a similar error with 2.6.29.2 with the -rt11 patch (from here) applied:

The latest one I have built is the 2.6.33-2-rt13 and I got an error like yours.
I disabled all staging drivers in the kernel config and it built OK.
I have no idea what disabling the staging drivers might do tp your system ;)

Best thing to do is read the help during the kernel config for each driver in staging---you most likely will not need any of them, and they are not really good quality yet anyway. Most of the realtek wifi drivers are junk, for example.

I built a 2.6.23-rt kernel and got nvidia working on Debian sid amd64.

I could not find Virtualization under Processor Type and Features in make menuconfig.
For me it was under Device IDs (I think that's it).

Also I was missing a couple of important pkgs at the start like libncurses5-dev but Googling sorted that out.
Now I'm going to recomplie with a couple of tweaks mentioned in the Alsa low-latency howto.

AFAIK the realtime features are included with stock kernel as of 2.6.36, no recompiling necessary. Unless you're a tweaker. Debian sid currently running 2.6.38-2 series.
