I attempted to apply patchs 4/6 and 5/6 to Bionic but ran into some
issues. Patch 4 does not apply and is trying to make changes to code
that never existed in mainline or Bionic. For example I don't see a git
history in mainline that the struct lpfc_sli_asic_rev ever existed and
the patch is trying to remove it:
--- a/drivers/scsi/lpfc/lpfc_hw4.h
+++ b/drivers/scsi/lpfc/lpfc_hw4.h
@@ -104,17 +104,6 @@ struct lpfc_sli_intf {

-

#define LPFC_SLI4_MBX_NEMBED false
Patch 5/6 looks like it will apply fine. Is there another version of the patch
4, or can you see if it's still needed?

Title:
Lancer A0 Asic HBA's won't boot with 18.04
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Bionic:
In Progress
Bug description:
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.
scsi: lpfc: Fix WQ/CQ creation for older asic's.
