[Bug 29787] random XRandR failures (i2c related?)

It seems that both the EDID errors and the XRandR failures do not occur when I
disable preemption (that, and I'm running 37-rc2 now). I'm currently rebuilding
-rc2 with forced preemption again, will alternate between those kernels for the
next few days to see what happens.

To give an idea of my current system activity: I'm compiling a kernel while
reloading all my tabs in Firefox, having two redraw-happy windows open at the
same time, and having three md5sum processes working on large files. System
load is peeking at 6.8 according to top (on a UP system), and yet I don't see a
single EDID or i2c warning in my dmesg.

This seems in line with my earlier conjecture that the problems are
latency-triggered. I will report back once I have more than the current 60
minutes of experience with the new kernel, with both forced preemption and no
preemption.
