Hi, I get a kernel crash if I use my NVME cache and write data on it.
dmesg, crash not included https://pastebin.com/D9huGDF4
Nothing happens if I copy just ~5gb on it, everything is fine.
As soon I copy more stuff on it crashs reproduceable after 10-30min (regardless if I use it as cache or directly copy onto it).
After it crashs (hard freeze of the system) I need to reboot and then it crashs much faster ~2-5min).
Temps are okay ~40°C and even with a DIY cooler directly on top nothing changes.
Can't grep a complete log because ssh dies too and no output happens.
What I tested so far and everything resulted in the same:
- RAM was tested with https://www.memtest86.com/ for a day and was okay.
- Nvme was replaced by an completely different one (different size and manufacture).
- Tried copy over network and local.
- Bios Update restore to stock settings etc.
- VM on or off doesn't matter.
- Complete reinstall with minimal config same result.
If I am not using the nvme cache everything is super stable and perfectly useable.
Same system at windows (did a test install to verify) has no problems with the nvme.
If anyone has a good idea what I may test or what log I need to provide pls ask (I am familiar with linux).
