Hi,

I have a server running on RHEL 5.4 64bit support. When I tried to add a new kernel with grsecurity 2.6.31.6 support, it shows a kernel panic upon reboot.

Pid: 1, comm: init Not tainted 2.6.31.6-grsec #1


Here is the Screenshot :

Please advise how can get fix or get past that error and run 2.6.31.6 kernel with grsec support.





Thank you.

please follow http://en.wikibooks.org/wiki/Grsecurity/Reporting_Bugs. for a quick guess, if you have SSP (stack protector) enabled, try to disable it.

I have the same error with 2.6.31.9.

Could you please advise how to disable SSP? Can't find it.

can you submit a proper bugreport please (also try 32.x, .31 is on its way out)?

it's called CONFIG_CC_STACKPROTECTOR under the 'processor types and features' menu.
