coreboot

How to reproduce:
Load a kernel and run Xorg, dmesg stacktrace will appear.
Run Palemoon (or FireFox) with graphics acceleration turned on, after a while of browsing everything hangs for half a second and then browser window becomes scrambled (and another stacktrace appears in dmesg)

examples of stacktrace:
