           Summary: Crash in libllvm with kernel based modesetting on
                    Radeon 7790
        QA Contact: xorg-team at lists.x.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: hrogge at googlemail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 7.7 (2011)
         Component: Driver/Radeon
           Product: xorg

I am using Kubuntu 13.10 and since my upgrade to this version I see a
reproducable crash during the start of the X-server. I am using the free Radeon
driver, not the propietary fglrx one.

Adding "nomodeset" to the grub boot manager suppress the crash.

I have already opened a bug in Ubuntu launchpad and added a lot of information,
but was unable to get any feedback about my problem:
