This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- zesty' to 'verification-done-zesty'. If the problem still exists, change the tag 'verification-needed-zesty' to 'verification-failed-zesty'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

On panic, kernel doesn't write mesg to /fs/pstore/dmesg* (Entry doesn't gets created at all) Contact Information = Ankit Kumar/kumar.ankit...@in.ibm.com ---uname output--- Linux seedlp2 4.10.0-15-generic #17-Ubuntu SMP Fri Mar 24 17:50:37 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux Machine Type = lpar Write to nvram failed ---Debugger--- A debugger is not configured ---Steps to Reproduce--- 1. Checked kdump kernel is loaded. 2. Triggered system crash # echo c > /proc/sysrq-trigger 3. /sys/fs/pstore/dmesg* doesn't gets created This issue can be reproduced after commit c950fd6f201 c950fd6f201 - pstore: Split pstore fragile flags It introduces PSTORE_FLAGS_DMESG, which is not set for PowerPC. Please include below commit 041939c1ec5 as this fixes this issue. commit 041939c1ec54208b42f5cd819209173d52a29d34 Author: Ankit Kumar <an...@linux.vnet.ibm.com> Date: Thu Apr 27 17:03:13 2017 +0530 pstore: Fix flags to enable dumps on powerpc After commit c950fd6f201a kernel registers pstore write based on flag set. Pstore write for powerpc is broken as flags(PSTORE_FLAGS_DMESG) is not set for powerpc architecture. On panic, kernel doesn't write message to /fs/pstore/dmesg*(Entry doesn't gets created at all). This patch enables pstore write for powerpc architecture by setting PSTORE_FLAGS_DMESG flag.
