some notes: - I do not experience this crash with fresh install of 16.04.1 ( with kernel 4.4.0-31 )
this starts to happen when: - the kernel gets updated ( I observed it clearly with 4.4.0-51 , 4.4.0-57 ) * it may have happened in 4.4.0-4* but I can't remember once a kernel update happens, even when I revert to 4.4.0-31 and uninstall the new kernel, this issue persists -- 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/1653015 Title: Random boot crash for Dell 7559 6700HQ with Ubuntu 16.04 Status in linux package in Ubuntu: Incomplete Bug description: boot log: Dec 29 06:31:42 xerusubu systemd[1]: Starting Network Manager...
