Hi.
After 2 successful upgrades from F29 to F30 and 2 successful full
installations, I decided to upgrade my main machine (that runs fine
since past november, installed in F28 then upgraded to F29).
No luck: unable to login (graphical, textual, ssh) except root.
The journal shows:
May 20 12:31:41 ... kernel: Linux version 5.0.16-300.fc30.x86_64

May 20 12:38:16 ... systemd[1864]: user@1005.service: Failed at step PAM
spawning /usr/lib/systemd/systemd: Cannot allocate memory
I add time, from a second textual console as root, to see the "systemd
--user" process reach more than 40 GB of memory before dying.
The lightdm session fails also with the same error.
Tries that do not solved this problem:
- re-installing kernel, systemd
- downgrading systemd to systemd-239-12.git8bca462.fc29
- fresh install in F30
Tries that solve this problem:
- adding mem=8192M to the kernel command line
this machine a 64 G of memory
- commenting pam_systemd.so from PAM (but want to keep it)
Any idea how to debug that?
Thanks a lot.
