Status in linux package in Ubuntu:

Status in linux source package in Wily:
  Fix Released

Bug description:
  We've made some progress on bug 1499869 , such that on Friday I actually had 
successful installs.
  An attempt at an install today shows a kernel stack trace early in the boot, 
then the initramfs not finding any network devices and thus failing to mount 
the iscsi root.

  The trace looks like this:

[Kernel-packages] [Bug 1502946] Re: kernel crash on m400 arm64 server cartridge

2015-11-16 Thread Luis Henriques

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-
wily' to 'verification-done-wily'.

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. Thank you!

  We've made some progress on bug 1499869 , such that on Friday I actually had

  An attempt at an install today shows a kernel stack trace early in the boot, 
then the initramfs not finding any network devices and thus failing to mount

@Tim: Please do - the dtb interface for numa is still in discussion, so
I think we can expect the OS/fw interface to change anyway.

2015-10-06 Thread dann frazier

fyi, though I do see this backtrace when booting up an X-Gene, in my
case it isn't fatal.

Rather, I'm hitting an issue later on where modules cannot load, and
*that* is fatal. It persists even w/ the numa patches removed.

Loading, please wait...

This appears to be the regression. Rebuilding the kernel w/
CONFIG_ARM64_ERRATUM_843419=n works around it.

commit bf0cdf4bfb785129798bc42d6ee8e2558f0934da
Author: Will Deacon 
Date:   Tue Mar 17 12:15:02 2015 +

arm64: errata: add module build workaround for erratum #843419

Title:
  kernel crash on m400 arm64 server cartridge

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  We've made some progress on bug 1499869 , such that on Friday I actually had 
successful installs.
  An attempt at an install today shows a kernel stack trace early in the boot, 
then the initramfs not finding any network devices and thus failing to mount 
the iscsi root.

  The trace looks like this:

ARM64 NUMA was added and enabled in 4.2.0-13.15, which apparently breaks
