We might have some progress here. After installing kexec-tools_2.0.6-0ubuntu2.1_i386.deb kdump is now loading and the initial reported problem that it was not even able to see the crash memory location is not showing up.
The remaining problem is that the kernel panic is not completing, the VM remaining stuck when the kernel panic is triggered which is a kernel situation. The problem is the same as in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1440103 Going to the initial thread, will you be able to see the changes for kexec that might be causing kdump to not load in the first place? root@ubuntu:~# sudo kdump-config load * loaded kdump kernel root@ubuntu:~# cat /sys/kernel/kexec_crash_loaded 1 root@ubuntu:~# dpkg -l | grep kexec ii kexec-tools 1:2.0.6-0ubuntu2.1 i386 tools to support fast kexec reboots root@ubuntu:~# dpkg -l | grep kdump ii kdump-tools 1:1.5.7-5 all scripts and tools for automating kdump (Linux crash dumps) root@ubuntu:~# uname -a Linux ubuntu 3.19.0-18-generic #18-Ubuntu SMP Tue May 19 18:30:59 UTC 2015 i686 i686 i686 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1400319 Title: [Hyper-V] Kernel panic not functional on 32bit Ubuntu 14.10 and 15.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kexec-tools/+bug/1400319/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
