I believe the current schedule for this cadence is June 14th.
** Description changed:
+ == SRU Justification ==
+ It was reported by Broadcom that an early asic model (A0) of their 16/32GB
+ HBA's doesn't boot with the lpfc driver in Ubuntu 18.04.
- We have discovered that an early asic model (A0) of our 16/32GB HBA's doesn't
boot with the lpfc driver in Ubuntu 18.04.
+ Bionic with the lpfc driver 12.0.0.0 can't see LPe16002-M6 but can see
+ LPe16002B-M6.
+
+ This bug is fixed by commits bf316c78517d and c221768bd49a, which are
+ both still in linux-next. Broadcom tested with this two commits and
+ confirmed they resolve the bug and allow the system to boot.
+
+ == Fixes ==
+ Currently in linux-next:
+ bf316c78517d ("scsi: lpfc: Fix WQ/CQ creation for older asic's.")
+ c221768bd49a ("scsi: lpfc: Fix 16gb hbas failing cq create.")
+
+ == Regression Potential ==
+ Low. Patches fix a current regression and are limited to lpfc.
+
+ == 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.
+
+
+
+ We have discovered that an early asic model (A0) of our 16/32GB HBA's doesn't
boot with the lpfc driver in Ubuntu 18.04.
After further review and discussion, this has been deemed a low risk
issue since early A0 HBA's were only ever shipped to OEMs for test
purposes. These cards were never shipped to end customers. We have
been working to replace those cards whenever we discover them.
We'll leave it up to Canonical to decide whether they want to pull this
in this single patch to an 18.04 subsequent update.
Symptom: Ubuntu 18.04 with lpfc driver 12.0.0.0 they can't see LPe16002-M6
but can see LPe16002B-M6
- Resolution: new lpfc driver patch update.
+ Resolution: new lpfc driver patch update.
