Reproducible: Always
I shutdown conserver (after rebooting the machine), hopefully this helps to avoid the crash.
Call Trace: Disabling lock debugging due to kernel taint If you can produce without a tainted kernel please feel to reopen.
(In reply to comment #2) > If you can produce without a tainted kernel please feel to reopen. How was the kernel tainted? And in which way? It is an unmodified Gentoo/Hardened kernel. It even says "Not tainted" for the first call trace...
Can the reporter try this again with the latest in tree hardened-sources-2.6.32-r8.ebuild. If it still crashes, please post your kernel config file so I can try to reproduce.
I cannot easily reboot my machine atm, thus I cannot test the kernel. Will report back as soon as I rebooted.
Is there any more on this from the reporter?
Running sys-kernel/hardened-sources-2.6.32-r10 now, conserver is running (but nothing connects to it via serial-console), no crashes so far.
