Hi Juerg, The problem appears to be fixed by updating the unit with the latest pieeprom-2025-02-11.bin that is shipping with Raspberry Pi OS
https://github.com/raspberrypi/rpi- eeprom/blob/master/firmware-2711/default/pieeprom-2025-02-11.bin. I've been unable to reproduce the issue after upgrading to this version (200+ tests so far). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2099935 Title: PCI initialization failure following kernel panic reboot on Raspberry Pi CM4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2099935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
