Public bug reported: My laptop repeatedly kernel panics after a botched "return from suspend" in my Samsung 900X laptop using (K)ubuntu 16.04.
Booting into 4.2.0-38-generic kernel seems to work fine. Up until this point 4.2 and four different 4.4 kernels functioned properly 90% of the time. Even then, roughly one-in-ten 'resumes from suspend' would panic, usually with blinking caps-lock LED. Cold-shutdown and restart would bring the system back up with little to no issue. This time was different, not sure why. Going through DebuggingKernelSuspend (https://wiki.ubuntu.com/DebuggingKernelSuspend) DID THIS: Shutting the lid of your laptop, which is set to suspend on close. DID THIS: Pressed the power button GOT THIS: kernel panic-- no blinking caps lock, just a single unblinking half-cursor at the top-left of the screen cat's of appropriate files are attached. If more is needed I am more than happy to oblige. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Attachment added: "suspend-bug.log" https://bugs.launchpad.net/bugs/1634214/+attachment/4762625/+files/suspend-bug.log -- 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/1634214 Title: kernel panic on resume from suspend with 4.4.0 kernels Status in linux package in Ubuntu: Incomplete Bug description: My laptop repeatedly kernel panics after a botched "return from suspend" in my Samsung 900X laptop using (K)ubuntu 16.04.
