  Then again triggered the crash on the machine using sysrq-trigger.

  But again the machine went to (initramfs) prompt since it could not
  load rootfs.

Hello,

So do you confirm that the latest kernel installed from the PPA also
solves the makedumpfile issue identified in
https://bugs.launchpad.net/ubuntu/xenial/+source/makedumpfile/+bug/1626269
?

Kind regards,

...Louis

[Kernel-packages] [Bug 1627126] Re: Machine crashes to (initramfs) after Triggering a crash - missing crc32c module

2016-09-26 Thread Louis Bouchard 
The kernel team has asked to see if you could test the kernel in the
following PPA :

  ppa:canonical-kernel-team/unstable

The kernel version is 4.8.0-17.19 and it is the kernel which may potentially
make it to the image. So if you can verify if the crc32c issue is present or not
on the ppc64el, this would be very helpful.

Kind regards,

...Louis
