Bug Description
[Impact]
The crashdump kernel fails to boot on HiSilicon D06, and likely other SMMUv3 ARM systems.
[Test Case]
sudo apt install linux-crashdump
Adjust crashkernel= parameter in /etc/default/
Add "arm_smmu_
sudo reboot (needed to add crashkernel= param)
echo 1 | sudo tee /proc/sys/
echo c | sudo tee /proc/sysrq-trigger
(Note to self - the following is needed on our systems w/ Mellanox adapters:
ubuntu@d06-3:~$ grep blacklist /etc/default/
KDUMP_CMDLINE_
[Fix]
3f54c447df34f iommu/arm-smmu-v3: Don't disable SMMU in kdump kernel
[Regression Risk]
Restricted to SMMUv3 arm64-based systems.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification- needed- disco' to 'verification- done-disco' . If the problem still exists, change the tag 'verification- needed- disco' to 'verification- failed- disco'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
See https:/ /wiki.ubuntu. com/Testing/ EnableProposed for documentation how to enable and use -proposed. Thank you!
