Comment 37 for bug 480220

I start to more and more suspect that this is more related to system load then to gl.

While playing around (I tried mesa from git and different kernel configurations) to see if I could find any more info I broke my network. So instead of doing things from ssh I changed VT while using KMS, killed X (as I did not see any reason to have it in the background), and started to recompile my kernel with an old known working config.
And while compiling I could notice that the console text did jump several times sideways, just like xbmc could do while having minor system load.

So can we rule out mesa, and take it that opengl just exposes this bug more, or is there something other I should try out?
