Hi, Dong. I have prepared a 5.4 test kernel for 20.04 with that patch applied for you to test here: https://launchpad.net/~magalilemes/+archive/ubuntu/test-kernels-3 You can add the PPA to your system by running `add-apt-repository ppa:magalilemes/test-kernels-3` and install (or upgrade to) the test kernel by running `apt install linux-generic -y`. To confirm that solves your issue, make sure, then, you're running the patched kernel by running `uname -a` and checking that the string `5.4.0-2000-generic #0+test-Ubuntu` is present.
Additionally, could you provide more details about the issue you found? For example, do those instances you mention fail to boot? After confirming that patch solves the issue, I'll submit the patch targeting the generic kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2067864 Title: iommu/arm-smmu-v3: Don't reserve implementation defined register space To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2067864/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
