When trying to modprobe ath9k or modprobe atl1c when running the .35-r5 kernel it causes an kernel panic (see the attached dmesg log) and modprobe segfaults. Trying to do anything after that kernel panic causes it to wait indefinatly and it never returns. Reproducible: Always Steps to Reproduce: 1.Run an 2.6.35-r5 kernel 2.modprobe ath9k or modprobe atl1c 3. Actual Results: Kernel panic and modprobe segfaults which causes any activity after the kernel panic to hang indefinetly Expected Results: modprobing should succeed and load my wlan or lan module successfully This was run from an freshly booted system, no commands prior had been issued except the users .bashrc and modprobe -r nouveau (which succeeded)

I tried hardened-sources-2.6.35-r6 that was pushed out today and that resolved the issue, same config. I still have the ability to reproduce the error if needed with an kallsyms enabled .35-r5a
what was the fix?
(In reply to comment #5) > what was the fix? > I never was able to reproduce this but let me clarify what grsec patches hardened-sources-2.6.35-r5 and -r6 are based on: -r5 -> grsecurity-2.2.0-2.6.35.7-201010232009 -r6 -> grsecurity-2.2.0-2.6.35.8-201010311944 The reporter also never gave and emerge --info, so I can't say if its x86 or amd64. Anyhow, if he says he can't reproduce it, I'm assuming its fixed. I'm closing this one for now. Reopen if needed.
