Is pc-kernel supposed to skip shipping those? Should there be modprobe.d in the core20 snap that prevents these known modules from loading by default? Also I'm not too sure about the watchdog modules exclusion, given that systemd can operate watchdogs by default, hence it shouldn't be too dangerous to autoenable them?

[Kernel-packages] [Bug 1831490] Re: kernel is out of memory and killed during a kernel sys_write operation
As the error is happening in ubuntu core 16 on i386, I couldn't install the apport snap due to is is not available for this arch (just for amd64). So I installed classic and generated the report from there, but I am not sure this information is the one you want. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1831490 Title: kernel is out of memory and killed during a kernel sys_write operation Status in apparmor package in Ubuntu: New Status in linux package in Ubuntu: Incomplete Bug description: This error is being reproduced on i386 arch when using the pc-kernel snap from beta or candidate. > sudo snap install test-snapd-tools > dmesg [15131.806107] audit: type=1400 audit(1559585825.240:93): apparmor="STATUS" operation="profile_replace" profile="unconfined" name="snap-update-ns.test-snapd-tools" pid=18240 comm="apparmor_parser" [15131.871610] vmap allocation for size 73728 failed: use vmalloc= to increase size.
