I using SLED over some years. On my laptop that runs every day for some hours I use a SSD. Some years ago we had to exchange one disk - ok. shit happen. Now I get failures again.
The laptop freeze totally and the HD controller is running continuously. Checking GSmartControl, no disk failures are found.
Can there be a issue with SSD and linux or specific SUSE?

@HANS-CHRISTOPH Hi, what about output from `smartctl -a /dev/sda`. Are you running btrfs, perhaps needs defrag/balance etc?

I use BTRFS as native file system - as SUSE suggest.

This is the result. The disc are not full, have space. It is strange. And this issues happen randomly. Sometimes I think it happens when using several programs and Internet? But I couldn’t find any issue here.

@HANS-CHRISTOPH Hi, that’s the correct one for a SSD. Can you confirm that the likes of fstrim, btrfs defrag, balance etc has been run?

It looks like all run well.
See, I have 2 SLED 15.2 running. One on my old desktop with a HD. There are no problems with disc.
One on my laptop with a SSD. I had exchanged one disk in past. The problems seems to be the same as last time. Random freezing of laptop. I that case, hard reboot is the only option. What I can see in that case is the SSD controller (LED) is running.
Searching for “Linux SSD freeze” I can see other had same problem.

Hi
So if you look at the times when the above services ran, does it correspond with when you get a freeze?
I also suggest enable the magic sysrq key… [https://en.wikipedia.org/wiki/Magic\_SysRq\_key](https://en.wikipedia.org/wiki/Magic_SysRq_key) use `cat /proc/sys/kernel/sysrq` to see the current value, can also setup a `/etc/sysctl.d/10-magic-sysrq.conf` file…

Hi
I’m not sure. The services run often and at night as can see on time stamp.
The sysrq value is 184 - ??
I can see I have to work with it a little bit more, but seems to have a lot of function. When freeze, ALT+F2 doesn’t work.

@HANS-CHRISTOPH Hi, have a read here: [https://www.kernel.org/doc/html/latest/admin-guide/sysrq.html](https://www.kernel.org/doc/html/latest/admin-guide/sysrq.html)
Try the key combo and press the keys in the required order press alt and hold, press sys rq key and release, then press the following keys one at a time R E I S U B and then release the alt key. System should reboot…

Now I found same failure on my Desktop as well. this has an regularly HD. I think I can relate that to Firefox. It happens wehn many windows are open and Firefox works in longer time.
I always happens when working with Firefox

@HANS-CHRISTOPH Hi, sounds like you might need to look at firefox tweaks, eg disk cache to reduce that.
How much system RAM?
Maybe reduce swappiness?
```auto
cat /etc/sysctl.d/98-swap.conf
#Reduce swappiness
vm.swappiness=1
vm.vfs_cache_pressure=50
```
