Thanks for the information.

Seems like it quite often triggers during the very first probing of 
graphics card during the initial X startup. Karsten is currently writing a 
tool that will safely restore the EEPROM contents to the card. When this 
gets done, testing will get much easier and hopefully we'll be able to 
isolate whether it is e1000e driver (I currently don't think so), DRM 
kernel code, or xorg 7.4 causing this.

Thanks,
