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.

THIS COMMENT ALSO ADDED TO (PARENT) BUG
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1699772
However, that bug has FixReleased (at least for 64-bit JVMs). 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.
I have chosen adding it to Bug 1699772 and also here, since my code example is
based on previously-provided test.c which I downloaded from Bug 1700270.

Stack Clash fix breaks JVM when launched from C
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have tested only with linux 4.10.0-24-generic on amd64. The attached
repro case:
- compiles a java class
- compiles a C program that initialises the JVM and calls a static method
from the java class
- launch the compiled C program.
Expected result:
the c program should execute the Java method and print some numbers in the
terminal
Actual result:
the c program segfaults while initialising the JVM
reverting to linux 4.10.0-22-generic amd64 fixes the problem. Since
the only change in the changelog is the Stack Clash fix and since I
remember reading that the JVM does tricky stuff with the stack, this
is a natural culprit.
It touches any program that initialises a JVM (so for instance Java
bindings in Postgresql or Java applets in firefox although the latter
have been deprecated and are only supported in firefox ESR now).
I attach the repro-case.
The issue happens with both openjdk-8-jdk from the repository and the
standard jdk 8 from oracle.

[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).
