Public bug reported:
After upgrading to linux-image-7.3.0-10-generic, the system fails to
boot and results in a purple screen / kernel panic.Rolling back to
linux-image-7.3.0-9-generic works perfectly fine and the system boots
normally.I did a clean install of Ubuntu 26.10. Attached are my system
logs collected by ubuntu-bug.
