Both the motherboard (DH67GD) and cpu (i5-2405S) are stock Intel just purchased via Newegg. USB live images from prior to when rc6 was enabled install and boot fine, but more recent images have the corruption/lockup problem, unless I pass the i915.i915_enable_rc6=0 parameter to the kernel. I installed an old precise image and upgraded it, then disabled rc6. The corruption looks like a scottish tartan, with bands of lines running horizontally and vertically. The screen is static (no pixels move). The mouse cursor does not move, the machine becomes unpingable. System is power cycled at this point by holding down the power button. The failure happens 100% of the time when rc6 is enabled. If plymouth is on it appears once plymouth kicks in; if plymouth is disabled and auto- login enabled, it'll make it to the user session, which displays properly for half a second, and then the corruption appears. The motherboard is reasonably generic but the cpu is one of the low power models. Guessing that might not play well with rc6? It also has a "mini" power supply, but don't know if that plays any role. I have an identical set of this hardware, which I'm going to assemble and see if it is similarly affected. The system is connected to its monitor via a KVM on the VGA port. Keyboard and mouse also connect to the KVM via a USB-to-PS2 adapter. I will experiment with different configurations of the inputs and outputs to see if varying them has any effect. Since the failure happens early in boot, I've been unable to ssh in and get dmesg output. Nothing gets printed to kern.log; indeed, some of the lockups have occurred in the middle of it writing debug output. I'm going to try setting up a netconsole.

The screen actually draws properly for a fraction of a second but then corrupts as shown in this photo and locks up hard. Can't vt switch or ssh in at this point.

I should mention the VGA connection I referred to earlier actually involved a VGA->DVI adapter. The motherboard has only DVI and HDMI outputs. This photo shows a direct-attached DVI monitor (KVM used only for keyboard/mouse). The corruption pattern is different in this case. With HDMI instead, the system still locks up post-grub but I see a blue screen (the monitor's standard 'no input' appearance) rather than corruption.

All the hardware bits are the same manufacturer and model numbers. However, I'm not reproducing the screen corruption on this system, whether rc6 is enabled or disabled. HDMI works on this second system, too (more or less). I'm going to try some hardware swapping to see if it can be isolated to a particular component.
