[Bug 1760284] Re: Regression, system unresponsible few seconds after showing gdm3, Sysrq doesn't work
If this issue doesn't happen to Bionic (which uses v4.15 based kernel), I think it's reasonable to upgrade. The bcmwl should work be able to build against v4.15. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760284 Title: Regression, system unresponsible few seconds after showing gdm3, Sysrq doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1760284/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1760284] Re: Regression, system unresponsible few seconds after showing gdm3, Sysrq doesn't work
I installed linux-kernel-4.16.0-041600-generic, I'm able to boot it but Broadcomm WiFI driver which I supsected as a reason fails: Examining /etc/kernel/postinst.d. run-parts: executing /etc/kernel/postinst.d/apt-auto-removal 4.16.0-041600-generic /boot/vmlinuz-4.16.0-041600-generic run-parts: executing /etc/kernel/postinst.d/dkms 4.16.0-041600-generic /boot/vmlinuz-4.16.0-041600-generic ERROR (dkms apport): kernel package linux-headers-4.16.0-041600-generic is not supported Error!

Meanwhile there was standard kernel upgrade 4.13.0-39-generic and it does work(including WiFi and with secure boot enabled(after manually signing wl.ko module)) in opposite to 4.13.0-37-generic and AFAIR 4.13.0-38-generic. So my problem was solved but I'm open do debug it further. One thing which changed also I did: apt-get install libelf-dev because of some warning from DKMS suggesting that during 4.16 kernel post-install. ** Attachment added: "bcmwl error from DKMS" https://bugs.launchpad.net/ubuntu/artful/+source/linux/+bug/1760284/+attachment/5107162/+files/bcmwl-6.30.223.271+bdcom-make.log ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Changed in: linux (Ubuntu Artful) Status: Incomplete => Confirmed ** Also affects: dell-sputnik Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760284 Title: Regression, system unresponsible few seconds after showing gdm3, Sysrq doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1760284/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
