Hi Daniel, hope you're doing well!
Thanks for reporting this regression. I worked a bit with qla2xxx back
in IBM LTC, so I can try to help.
There are indeed a few 'stable' fixes for qla2xxx between 4.15.0-72 and -73
(none on -74).
Well, apparently not so stable.
And none of their upstream commit IDs are marked in Fixes commits on mainline,
sadly; so no immediate indicators of the culprit.
There are more fixes in Ubuntu-4.15.0-88.88 (yes) currently in bionic-proposed.
And a few more fixes in master-next (just in git, not yet released.)
So,
1) Could you please try the kernel packages from bionic-proposed first ?
2) And if doesn't help, build the packages from master-next ? (or I can give
you test packages)
Hopefully either may help. Otherwise, we can check more recent kernel
versions.
Thanks,
Mauricio

Title:
qla2xxx no longer detects LUNs with 4.15.0-74+ on IBM BladeCenter
Status in linux package in Ubuntu:
Incomplete
Bug description:
We have an IBM BladeCentre Hx5 with a number of blades running Ubuntu
18.04.3. Storage is attached over Fiber Channel.
They all boot fine with 4.15.0-72 - the qla2xxx detects all the LUNs.
On 4.15.0-74 and 4.15.0-76, the qla2xxx driver loads but the LUNs are
not detected. This breaks the boot. rescan-scsi-bus.sh is also unable
to find the LUNs. Reverting to the 4.15.0-72 kernel works.
lspci reports:
