From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've experienced random stuff like that in past - not exactly the same though and not that chip.
I'd suspect power issue, either cpu and/or gpu causing a spike that results in some voltage rail to go unstable. More likely GPU, unless your applications are really thrashing all cpu cores.
How old PSU? how much headroom? how good brand of PSU? Might also be a motherboard power management issue.
Also - it might not hurt just to unplug and reseat every power cable.
What is your:
Versions?
Additionally, what does the kernel logs tell you when you get a green screen?
Not a 7900 but my 5900 does for sure.
Seems to be a common issue. Lots of posts point to the PSU as the issue. Do a search on your card and green screen + linux and see all the results. Good luck.
