** Description changed: As discussed in Bug #1833322: "Please consider no more having irqbalance enabled by default (per image/use-case/TBD)" (https://bugs.launchpad.net/ubuntu/+source/ubuntu-meta/+bug/1833322) the irqbalance package will no longer be installed by default in Noble. So - as a test I removed the package from my Raspberry Pi 5 running Mantic, - after which the Pi 5's power button no longer worked to poweroff the - system. Re-installing irqbalance caused the button to work again. + as a test I removed the package from my Raspberry Pi 5 running Mantic + Server, after which the Pi 5's power button no longer worked to poweroff + the system. Re-installing irqbalance caused the button to work again. With irqbalance installed I see these messages at boot time: kernel: input: pwr_button as /devices/platform/pwr_button/input/input1 systemd-logind[694]: Watching system buttons on /dev/input/event0 (pwr_button) Without irqbalance I see this: kernel: gpio-keys pwr_button: Unable to get irq number for GPIO 0, error -6 So the Raspberry Pi 5 might still need irqbalance installed, or perhaps there's a better solution for enabling the button. I have the following appended to the Mantic default /boot/firmware/config.txt: # Trickle charge the RTC battery (default: don't charge) dtparam=rtc_bbat_vchg=3000000 # Enable the PCIe external connector dtparam=nvme # Force PCIe Gen 3.0 (default: Gen 2.0; not certified for Gen 3.0) # dtparam=pciex1_gen=3 # Enable second serial port on GPIO 14 & 15 (default: disabled) dtparam=uart0 # Change activity LED behavior (default: blink for MMC access) dtparam=act_led_trigger=heartbeat # Disable Bluetooth (not wanted on a server) dtoverlay=disable-bt-pi5 # Enable PPS on GPIO 18 for MAX-M8Q GNSS HAT dtoverlay=pps-gpio,gpiopin=18,capture_clear
