cxlflash update request in the Xenial SRU stream

------- Comment From <email address hidden> 2017-07-05 14:25 EDT-------
Below list of patches are pulled into upstream 4.13 kernel. If it is not too late, we would like to have them in the Xenial 16.04.3 HWE v4.10 kernel as well. These patches include miscellaneous fixes and it would be helpful to have them in 16.04.3 kernel.

Hi Uma,

New build with the requested patches are available at:

http://pokgsa.ibm.com/~vaoqui/public/bz154010/v3/

Please test it and let me know if this can already be mirrored.

Thanks

Victor,

I verified the patched kernel from the given location. It passes the basic FVT test. Thanks for the quick turnaround.

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. Thank you!

Uma,

Could you please test the kernel and show the results?

Thanks
