Hi,
i'm having the following 2 Issues:
1. Stability issues, The System freezes randomly an i have no hint to get rid of the freezes.
2. At bootyp the Swap Partition won't be mounted. If the bootup ist completet and i type "swapon -a" - everything ist ok
Because i'm a Newbie - i don't know how i could get rid of these Problems.
If you can tell me what i could try or what i schould check - please tell me.
thx

Define 'freeze'. For how long, what were you doing at that time, does systemd's journal, htop or iotop show what could be the cause, do you have to reboot to make it go away?
Post your /etc/fstab.

Not a Kernel issue, moving to NC...

thx for you answer. I think i have to explain what i mean with "freeze" --> the pc isn't responding, that mean - no key input, no ssh responding. The PC has noch Graphical interface, only console and is uptodate and acts at home as my "server" thats why i cant say what it is exactly doing.
I think the only way is to get all log-files and search for the issue - what logs do i have to check?
How could i check why my swap partition couldn't be activatet at startup, but after login and "swapon -a" everything is fine?

And i decrypt my /root partition with a key on my usb-stick at boot-time.

Check systemd's journal.
Have you tried using the stock kernel?

Yes, i'm having the same Issues, with Stock Kernel.
I don't know how to see the Systemd's Messages for boot-Time. If i Type:
journalctl /usr/lib/systemd/systemd -b
i only get this, but no output for the boottime?!

Any Suggestions?

There is some weirdness with btrfs right now where it is causing deadlock conditions. It could be related? I believe I saw another user on the forum also using btrfs with encryption having problems. The encryption may make it more likely to occur (just speculation)?
https://www.mail-archive.com/linux-btrf … 36238.html
On my system it seems (assuming it is related) to result in one or more cores becoming 100% cpu use and "locked". Trying to kill the process with even "kill -9" is impossible. Based on this message the fix should hit the mainline kernel soon.
I think systemd now usually handles the swap, no? I use a loopback swap file on mine since it's all btrfs. But are oyu using an encrypted swap setup of some sort? If so maybe see https://wiki.archlinux.org/index.php/Dm … encryption If not maybe see https://wiki.archlinux.org/index.php/Sw … by_systemd
