Comment 2 for bug 2018612

So this is a crash of the guest kernel from a CirrOS 0.5.2 image. That image contains a 5.3 kernel which is no longer supported. The 0.5.2 image is a minor update of the original 0.5.1 image which was built before the release of Focal. It was pulling in the HWE kernel which at that time was a 5.3 kernel. The updated 0.5.2 CirrOS image apparently didn't upgrade the kernel hence it's also on an unsupported 5.3 kernel.

The current (supported) Bionic HWE kernel is 5.4 (same version as the Focal release kernel).

Long story short, you're running on old/unsupported kernel, so the first step is to upgrade the kernel and see if the problem goes away. Also CirrOS is not a supported distro/image, so closing the bug as 'invalid'.

We can revisit if you run into issues with a supported 5.4 kernel. In that case, please open a new ticket.
