For me on my UL30VT with ubuntu 15.04 it was: gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13)
And cat /proc/version Linux version 3.19.0-15-generic (buildd@komainu) (gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13) ) #15-Ubuntu SMP Thu Apr 16 23:32:37 UTC 2015 Nevertheless, I discovered and remove some old gcc versions and re-installed all dkms packages, but still have the same behaviour as detailed above. I wonder if there are any ul*0vt laptops that are still working out there? I will try installing bbswitch on a clean install of ubuntu when I have time -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1318040 Title: bbswitch prevents suspend and taints kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bbswitch/+bug/1318040/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
