Yeah, this is a known issue with debug kernels. Grab the first rc5 build out of koji and it will have the debug options disabled. *** This bug has been marked as a duplicate of bug 735268 *** Do you plan fix it? Or live all time with workaround? (In reply to comment #2) > Do you plan fix it? Or live all time with workaround? The kernels starting with the Beta release always have the debugging options disabled. The impact of them won't be present in the GA. Enabled debugging options should not be so kill performance. The more this happens only on processors from AMD. Tested on the Intel Core 2 Duo processors, too slow. Why not make the switch as an option to debug? Now I couldn't find koji kernel rc5 build. How find it? |
