I suspect this is a duplicate of LP: #2130734 Could you run "sudo rpi-eeprom-update" on your Pi 4 and report the date next to "CURRENT:"? In order for the questing boot method to work this needs to be 2022-11-25 (Nov 25 2022) or later.
If it's earlier, try running "sudo rpi-eeprom-update -a" and rebooting. This should bring the EEPROM up to a reasonably recent state and ensure the boot succeeds. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2131273 Title: Upon upgrading Ubuntu to 25.10 from 25.04, new kernel 6.17 cannot be used and 6.14 remained To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/flash-kernel/+bug/2131273/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
