Hi, problem still present on linux-image-4.8.0-58-generic with these conditions: - while executing JVM launched from >>32-bit<< C (on 64-bit kernel) - defining "higher" JVM stack size (eg. -Xss2048k JVM argument) => causes JVM segmentation fault Attached test case (sources + binary + output logs): Bug1699772_i386_jvm_segfault_problem.tgz test_case1.c (32-bit) => using -Xss1024k => RUNS OK. test_case2.c (32-bit) => using -Xss2048k => Segmentation fault. test_case1.c (64-bit) => using -Xss1024k => RUNS OK. test_case2.c (64-bit) => using -Xss2048k => RUNS OK.

I guess it should be also fixed for 32-bit JVMs launched from C on 64-bit kernel. I'm not sure, whether it would be better adding this comment just to Bug 1699772, or just to this ("duplicate") Bug 1700270, or creating just another bug ID.

[Kernel-packages] [Bug 1283938] Re: [Samsung NP535U4X-S01TH] Ubuntu 14.04 blank screen after wakeup from sleep
HI, my setup: - Lenovo T530 with NVIDIA Corporation GF108M [NVS 5400M] (rev a1) - Ubuntu 14.04 with mainline kernel 3.14.9 - NVIDIA driver nvidia-331-updates: My computer hanged during hibernate resume just after reading the image from the disk. I found working solution by reading non-editable file: /usr/lib/pm-utils/defaults This worked for me (so now hibernation works again): 1.) echo "HIBERNATE_RESUME_POST_VIDEO=\"no\"" | sudo tee /etc/pm/config.d/hibernate 2.) Just to be sure (probably unnecessary): sudo update-initramfs -u sudo reboot 3.) Test sudo pm-hibernate 4.) Alternative test: # press ctrl+alt+1 (go to virtual terminal) sudo pm-hibernate -- 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/1283938 Title: [Samsung NP535U4X-S01TH] Ubuntu 14.04 blank screen after wakeup from sleep Status in “linux” package in Ubuntu: Incomplete Bug description: In 14.04 after wakeup from suspend, the notebook screen goes blank while the OS and the hardware is awake (I can also press Ctrl+F1 and Ctrl+Alt+Del to reboot the system).
