Hi guys!
In the last couple of weeks I had the following behaviour occur a few times:
1) / gets reoumted to r/o
I always notice this quite quickly because stuff stops working, vim won't save my files, etc.
2) Then I check with mount and indeed, / is ro:
/dev/mapper/vgssd-root on / type ext4 (ro,noatime,discard)
3) When I try to remount it, it says:
# mount -o remount,rw /
mount: /mnt not mounted already, or bad option
4) Meanwhile dmesg shows this:

5) Reboot fixes everything, laptop works perfectly for 1-2 weeks
System Info:
- Newest Kernel, no custom kernel Stuff
- ext4 on LVM on LUKS
- Fairly Old Lite-on SSD (4+ Years), but extended SMART Test says SSD is fine
- Intel i7 4th gen
Any ideas, other than a dying SSD? Is there any better way to test the SSD besides SMART?
Thanks!

[33391.844673] sysrq: SysRq : Emergency Remount R/O # ro remount begins
This seems to show the remount was in response to sysrq see Keyboard_shortcuts.

I did consider this initially, but it seemed extremely unlikely, due to how I was used to invoke the Sysrq combinations on my old keyboard.
However, I did not consider that on my new keyboard I only need to press PrtSc+Alt (which are neighbouring keys) and {r,e,i,s,u,b}.
Dumb oversight on my side
Thanks!
