Sorry, didn't realize you aren't the OP.
The release notes for 341.21 say it is the first driver to support the K80:
So it is possible that hashcat is triggering some bug in this new driver, or vice versa. You may need to hop on IRC and work with atom directly on this.
The other thing that comes to mind is that I don't know how well synced the Tesla driver versions and Geforce driver versions are. "331.67 or later" in Geforce terms may not mean the same thing in Tesla terms. I recognize that this is the latest driver, but it is possible that this driver doesn't have something that hashcat requires.
There aren't very many Tesla users around here since they have extremely low Perf/$ for hash cracking, so it's entirely possible that this issue may affect all Tesla users on 1.31 and we just don't know about it. Or, since the K80 is a new card, it's also entirely possible that this is an isolated issue affecting only K80 users (all two of you.) Either way I think the next step is probably to involve atom in this discussion.
