Is it possible that the issue might be related to the hardware watchdog timer? I note the following lines in the dmesg output:
[ 2.214004] bcm2835-wdt bcm2835-wdt: Broadcom BCM2835 watchdog timer [ 2.288820] watchdog: Delayed init of the lockup detector failed: -19 [ 2.295372] watchdog: Hard watchdog permanently disabled Is this expected output for a CM4? I've tried researching how to enable it but am a little out of my depth. cat /boot/config-$(uname -r) | grep BCM2835_WDT CONFIG_BCM2835_WDT=y This suggests the BCM2835 support is compiled into the kernel. Are there any other configuration items I can modify to properly enable the hard watchdog? -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
