Title:
[Hyper-V] Kernel panic not functional on 32bit Ubuntu 14.10, 15.04,
and 15.10
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Xenial:
Fix Released
Status in linux source package in Yakkety:
Fix Released
Bug description:
While testing the final build of 14.10 32bit we found that kernel
panic cannot be activated for an installation on a Hyper-V VM.
Repro rate: 100%
Repro details:
Hyper-V: Server 2012 R2
VM: Ubuntu 14.10 32bit
Kdump is enabled in the config file at /etc/default/kdump-tools
Different crashkernel values used in grub.cfg – 128M-:64M | 256M-:128m
| 384M-:256M
VM settings: 2 cores, various RAM sizes attempted: 1, 2 or 4 GB – this
in combination with the values for crashkernel.
Trying to start the kdump service:
root@ubuntu1410i386:~# /etc/init.d/kdump-tools start
Starting kdump-tools: Could not find a free area of memory of 0x9f000 bytes...
locate_hole failed
* failed to load kdump kernel
---
root@ubuntu1410i386:~# cat /sys/kernel/kexec_crash_loaded
0
If the conversion from hex to dec is right, the mentioned memory mapping of
0x9f000 bytes is equal to 651264 (bytes), so under 1MB. This is not then
related to the RAM allocation nor the crashkernel value used.
