The linux-firmware package only includes up to version 8. I will try with version 9 in a bit. The 3.17 kernel can also use version 10. I will try that as well. ** Tags added: kernel-bug-exists-3.17 ** Tags removed: kernel-bug-exists-3.17 ** Tags added: kernel-bug-exists-3.17.4 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1395553 Title: iwlwifi contiually crashes Status in linux package in Ubuntu: Incomplete Bug description: I am getting "Microcode SW error detected" constantly in my dmesg output.
