Description:
I was in my regular user session and was kicked and banned from said session seemingly without warning; rebooting allowed me to log in again, but that's not the issue. The log file showing the actual issue, which looks to be related to an nfs kernel module.

I posted here first just to verify that the issue is not due to Arch's linux-grsec .config, so I can hop on their forums if need be.

This looks like a genuine bug either in the module or grsecurity, so reporting it to the forum would be best. My guess is that it's an issue in the KSTACKOVERFLOW feature.
