grsecurity reload renders machine unresponsive

[Dwokfur]

I've recently upgraded to hardened-sources-3.11.9-r1 (incorporates grsecurity-3.0-3.11.9-201311242034) and started using gradm-3.0-201311242038. After booting the new kernel, the policy gets loaded and I can authenticate myself as an admin. However upon issuing a policy reload, the machine becomes unresponsive. Including no reactions to SysRq. Unfortunately there are no kernel log messages related to the event. I can only see new log entries after it comes back.

Any known issues or suggestions related to the symptom?

Thx: Dw.

update to the latest grsec patch (by hand for now) as it fixes a few problems with the new atomic reload code.

gradm-3.0 using hardened-sources-3.12.4 containing an upgraded grsecurity patch solved the problem.
Policy can be reloaded properly without a crash and prior user mode helper log messages have also gone (related to some openrc shell scripts).
I test the kernel a bit more.

Thanks: Dw.
