Public bug reported:
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:

Let me know if you need any more details. I attach a version.log and
lspci-vnvn.log from a working -72 boot.
