** Description changed:
+
+ SRU Justification:
+
+ [Impact]
+
+ Cloud images using the arm64 minimal kernel cannot detect config drive
+ cloud-init datasources in openstack. This seems to be due to openstack
+ environments using or emulating a sym53c8xx scsi controller for the
+ config drive.
+
+ This seems to affect both minimal cloud images as well as generic arm64
+ kernels.
+
+ [Fix]
+
+ Enable the SYM53C8XX_2 driver in generic arm64 kernels. This allows the
+ drive to be successfully mounted.
+
+ [Test Plan]
+
+ To reproduce: register and launch an arm64 minimal cloud image in
+ openstack configured to use a block disk bus and verify that cloud init
+ can mount the config drive.

+ ----------

+
Cloud images using the arm64 minimal kernel cannot detect config drive
cloud-init datasources in openstack. This seems to be due to openstack
environments using or emulating a sym53c8xx scsi controller for the
config drive. This doesn't work for initrd-less boot, as in the case of
minimal cloud images.
To reproduce: register and launch an arm64 minimal questing cloud image
[1] in openstack configured to use a block disk bus and verify that
cloud init cannot mount the config drive.
