[Bug 1743856] Re: EDAC, sb_edac: Backport 1 patch to Ubuntu 17.10 (Fix missing DIMM sysfs entries with KNL SNC2/SNC4 mode)

[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!

SRU Request submitted:
https://lists.ubuntu.com/archives/kernel-team/2018-March/090516.html

** Description changed:

- The sb_edac needs additional patch to enable EDAC to know of the existence of 
some DIMMs attached to channels while figuring out the size of the DIMMs and 
the cluster mode is SNC2 or SNC4. 
- All the thread connected with this issue is described here 
https://www.spinics.net/lists/linux-edac/msg08170.html. 
+ == SRU Justification ==
+ The sb_edac needs this patch to enable EDAC to know of the existence of

+ and the cluster mode is SNC2 or SNC4.
+ 
+ All the thread connected with this issue is described here

+ 
+ == Regression Potential ==
+ Low. Limited to EDAC checking dimm capacity.
+ 
+ == Test Case ==
+ A test kernel was built with this patch and tested by the original bug 
reporter.
+ The bug reporter states the test kernel resolved the bug.
+ 
  
  Please backport the following patch:
  
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?id=24281a2f4ca569d44e44e4cbc500cf08e7bb4c36
 to solve the sb_edac driver issue on Ubuntu 17.10.
  
  Thank you!

[Bug 1743856] Re: EDAC, sb_edac: Backport 1 patch to Ubuntu 17.10 (Fix missing DIMM sysfs entries with KNL SNC2/SNC4 mode)

[Anna]

I verfied it with the kernel: 
Linux [*]4 4.13.0-36-generic #40~lp1743856 SMP Tue Feb 27 19:57:05 UTC 2018 
x86_64 x86_64 x86_64 GNU/Linux

and the output of the following command: 
ls -la /sys/devices/system//edac/mc/mc0/dimm

seems to be good:
dimm0/ dimm1/ dimm2/ dimm3/ dimm4/ dimm5/

Thanks!

[Bug 1743856] Re: EDAC, sb_edac: Backport 1 patch to Ubuntu 17.10 (Fix missing DIMM sysfs entries with KNL SNC2/SNC4 mode)

[Joseph Salisbury]

I built a test kernel with commit 24281a2f4ca56.  The test kernel can be 
downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1743856

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!
