A new Focal kernel that contains (among the other things) several scsi/qla2xx fixes is in -proposed now:
linux-image-generic | 5.4.0.13.16 | focal-proposed | amd64, arm64, armhf, ppc64el, s390x
could you test that?
In case that doesn't fix you issue, can you give us the output of "dmesg / cat /sys/class/fc_host/host*/symbolic_name / multipath -ll / lsscsi" of a working kernel? You mentioned Bionic is working fine on this setup.
