Ubuntu Focal
ga kernel
This problem was originally reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=1783075
Using the linux-generic-hwe-20.04-edge packages resolves the issue.
We hit this while exploring storage options for PS5 where we would like to put a Optane as cache device in front of a NVMe SSD backing device with 512 byte optimum I/O size.
While the problem appears to be fixed for the kernel we file this bug to document a need for Focal hwe-edge images for commissioning/deploy in MAAS. |
