FYI: SolidRun Honeycomb/ClearFog LX2K users depend upon this feature as
well (ARM_SMMU_DISABLE_BYPASS_BY_DEFAULT=n); despite this original issue
being filed for Cavium boards, it's still true for more recent hardware
as well.
Thus, please don't remove it without compatibility testing. Thanks!

Title:
arm64: loop on boot after installing linux-generic-hwe-18.04-edge
/bionic-proposed
I bisected this down to the following commit, which suggests we need a
fix for ThunderX IOMMU config, but can consider disabling
ARM_SMMU_DISABLE_BYPASS_BY_DEFAULT until then. To confirm, I verified
that 5.3 boots fine with arm-smmu.disable_bypass=n on the cmdline.
commit
I can reproduce.
Moving to 'linux' package because:
- linux-meta-hwe-edge is a meta package, it doesn't actually provide the kernel
- While linux-hwe-edge is the package in which we're seeing the bug, the
kernel team actually seems to always track such bugs in the 'linux' package
from whence
adding machine console log after 'sudo reboot':
