Bug description:
[Impact]
Azure kernels fail to boot on large Azure instance types.
[Fix]
revert 10b9a1068ba301b6458a308c749eb0b93951010c ("scsi: core: Cap
scsi_host cmd_per_lun at can_queue") from "UBUNTU: upstream stable to
v4.14.240, v4.19.198"
This commit originates from an unreleased kernel (5.14-rc1). According
to the commit log it purports to head off possible future problems. It
does not appear to address a specific bug. It has been backported to
4.14.y and 4.19.y.
[Test Plan]
Install and boot on an Azure Standard_D48_v3 instance.
[Where problems could occur]
iscsi requests could hang
