Bug description:
  == SRU Justification ==
  IBM is seeing a crash on Power9 when running on Artful. 
  This issue happens only when disabling RPT ("disable_radix"), which is not 
the default in Artful.

  
  These fixes are already in Bionic master-next, so they are only being 
requested 
  in Artful.

  b5048de04b32 ("powerpc/mm/slb: Move comment next to the code it's")
  21a0e8c14bf6 ("powerpc/mm/hash64: Make vmalloc 56T on hash")

  == Regression Potential ==
  These commits are specific to powerpc and fix a crash.

  == Test Case ==
  A test kernel was built with these patches and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.

[Kernel-packages] [Bug 1739498] Re: Ubuntu 17.10 crashes on vmalloc.c

2018-03-19 Thread Stefan Bader 
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-
artful' to 'verification-done-artful'. If the problem still exists,
change the tag 'verification-needed-artful' to 'verification-failed-
artful'.

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!

[Kernel-packages] [Bug 1739498] Re: Ubuntu 17.10 crashes on vmalloc.c

2018-02-05 Thread Joseph Salisbury 
I built an Artful test kernel with the three patches listed in comment
#6.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1739498

Can you test this kernel and see if it resolves this bug?

Note, to test this kernel, you need to install both the linux-image and
linux-image-extra .deb packages.

Thanks in advance!

I'll build a test kernel for those three patches for testing.  Once
confirmed they fix the bug, I can submit an SRU request.

[Kernel-packages] [Bug 1739498] Re: Ubuntu 17.10 crashes on vmalloc.c

2018-01-02 Thread Joseph Salisbury 
If we don't yet know what patch in v4.15-rc4 fixes the bug, we can
perform a "Reverse" bisect to identify the fix.

Can you test v4.14-rc1, so we can narrow down the last bad kernel
version and the first good one?  It can be downloaded from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14-rc1/
