5U84 - ses driver isn't binding right - cannot blink lights on 1 of the 2 5u84

I built a Yakkety test kernel with commit 9373eba6cfae. The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1693369/yakkety/

Can you test this kernel and see if it resolves this bug? Xenial needs some prereq commits, so I'm working on identifying them and and should have that test kernel shortly.

Thanks for the quick turnaround! Unfortunately, I only see amd64 packages there. Any chance I could get a ppc64el package?

I built a ppc64el package. It can be downloaded from the same link:

http://kernel.ubuntu.com/~jsalisbury/lp1693369/yakkety/

I also built a Xenial test kernel with commit 9373eba6cfae. It required three prereq commits:
 scsi: sas: provide stub implementation for scsi_is_sas_rphy
 ses: fix discovery of SATA devices in SAS enclosures
 scsi_transport_sas: add function to get SAS endpoint address

The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1693369/xenial

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

The fix for this has been accepted and is in linux-next commit 62e62ffd95539b9220894a7900a619e0f3ef4756.

https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next/+/62e62ffd95539b9220894a7900a619e0f3ef4756%5E%21/#F0

Please backport into Ubuntu 16.04. I have run this patch in Ubuntu and confirmed that it fixes the issue we see.

Does commit 62e62ffd95 supersede commit 9373eba6cfae?

Both commits are required to fix enclosure handling.

I built one more Xenial test kernel. This time the test kernel has both commits and the three prereq commits.

The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1693369

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

I tested this kernel and it works. There are some other fixes related to SES that are currently only in 4.8/4.10 kernels, so we need to determine whether anything else is required.

I am assuming that this fix will also be going into 4.8 and 4.10, right?

Sorry for the delay. I'll submit an SRU request for this bug.

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-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

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!

Hello IBM,

Could you please verify the fix with the xenial and/or zesty kernels currently in -proposed?

Thank you!

I did a scratch install of 16.04-updates, kernel 4.4.0-98 #121. This works with the storage enclosures and the required symlinks all appear. This issue may be closed.
