Patches for the cxlflash SCSI driver are in the process of being
upstreamed as to 4.4. This is to get those patches into the next

Patch 1 correctly initializes a spin lock so that it may be used with instrumentation when
debugging issues.

Patch 2 fixes a critical issue where a kill off of cxlflash superpipe processes can lead to a hang or Oops.

More details can be found in the patch commit message.

Thanks Leann. IBM is launching new CAPI enabled servers from OpenPOWER
(made by Tyan and Wistron and rebranded as IBM) and I suspect this is
required.

Cheers,

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!
