Hello,

I'm doing some troubleshooting for newest issue which happened to me several days ago. I'm using gentoo hardened kernel 2.6.16-r11 and as i had to reboot due to new network adapters installation, i decided to test and enabled this option. First, system booted OK, but I experienced random hard reboots later. No info, no logs...just as if someone pressed reset button. Not sure if this option is the problem, or the driver for r8169 ethernet is faulty, or there is a bug in ethernet bridging support..or some combination - these 3 changes were done prior to the issue.

Any ideas what may cause the problems?

EDIT: system is amd64

i'm pretty sure that NOELFRELOCS won't cause a kernel crash like that, at most it will cause apps failure if they try to load libraries with text relocations (something that is forbidden by the amd64 ABI, so this should really never occur unless you have 32 bit userland libs with textrels). you should probably investigate the other changes.
