[Touch-packages] [Bug 1535840] Re: systemd ignoring /etc/modules due to blacklist
Confirmed this still exists in 22.04 (Jammy Jellyfish), with symptoms being SystemD booting always into "degraded" state because wdmd.service (Watchdog Multiplexing Daemon) will always fail due to missing watchdog kernel module(s). Check this is the case with: sudo systemctl status sudo systemctl list-units --failed The solution suggested by @ishworgurung works to allow iTCO_wdt (and other watchdogs) to be loaded by the kernel during boot appropriately. Then, wdmd.service starts up successfully and SystemD enters successful "running" state (assuming all other SystemD services are working properly). However, every kernel package update will place another blacklist file in /lib/modprobe.d/blacklist_linux_$(uname -r).conf. So this is only a temporary workaround until these modules are not blacklisted by default. The blacklist files are part of linux-modules-$(uname -r) package(s).

[Touch-packages] [Bug 1535840] Re: systemd ignoring /etc/modules due to blacklist
In some systems, like embedded devices, it is needed to have the control of the (hardware) watchdog in the application itself, not managed by systemd. In this case, the solution of /etc/default/watchdog doesn't work. Then, if all modules are blacklisted, I have to create a script and manually load them, this is not the best thing, especially for a watchdog! So, this issue still exists for watchdog not managed by the watchdog daemon.

[Touch-packages] [Bug 1535840] Re: systemd ignoring /etc/modules due to blacklist
This issue makes it annoying to load watchdog drivers, as systemd now supports hardware watchdogs they'd have to be added to rc.local or a custom service. The pre-systemd behaviour only applied the blacklist with udev, not when processing /etc/modules(-load.d) so that they could be prevented from loading automatically unless explicitly listed by the user.

Thanks for the tip, will try that. What is extremely frustrating is that to unblacklist a module you have to edit 4 different, some dynamic files.

[Touch-packages] [Bug 1535840] Re: systemd ignoring /etc/modules due to blacklist
Generally me work-around so far has been to avoid systemd! However, where that is not an option you might be able to edit /etc/default/watchdog so the module is loaded on watchdog start-up. It is not ideal as you might have some other reasons for wanting the /dev/watchdog virtual file to be testable without the watchdog having started though (e.g. automated install script that probes harder support, etc). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1535840 Title: systemd ignoring /etc/modules due to blacklist Status in systemd package in Ubuntu: New Bug description: I tried the daily build of 16.04 32-bit to test out the watchdog daemon code.
