Is it mainline kernel? I have the same error with it. ilia@ilia:~$ uname -a Linux ilia 3.11.0-4-generic #9-Ubuntu SMP Mon Aug 26 15:21:06 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
I have two videocards in my system: 1) integrated into A8-5500 APU with display connected 2) discrete radeon 7870 without display, only for OpenCL computations. On my main system (raring 13.04, kernel 3.8) I use fglrx without any problem, both of videocards works fine. On the second system, 13.10, I use radeon driver for the mir works - and errors appears. Also, without trying any opencl computatons on the second system. ** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1216749/+attachment/3791154/+files/dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1216749 Title: "ib ring test failed (-35)" and other errors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1216749/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
