System freeze with 5.13.1-rt1-xanmod1
Hello,
I recently updated my kernel from 5.11.12-rt11-xanmod1 to 5.13.1-rt1-xanmod1 and started experiencing freezing. I fell back to the previous version to regain stability. I hope I've captured the right logging entries, as kernel troubleshooting is quite far outside of my wheelhouse.

Please let me know if anything else is needed.
Thanks, cj0nes
EDIT: I just realized that the kernel I updated to is classified as "In Development". I did not notice that before I updated. Well, I guess this issue could possibly aid development then.
Hi,
I am also experiencing system freezes and crashes on pop-os with the production ready 5.13 kernel. The system completely freezes (unable to do anything, SSH won't work either). Sometimes it will also completely crash after being frozen for a couple of seconds and reboot the system.
How has the above log been obtained? So that I could also supply one in hopes this get fixed. At the moment the freeze/crash happens about once per day, this is obviously something that needs to be fixed.
Thanks
How has the above log been obtained?
I believe I pulled it from /var/log/kern.log
@cj0nes: Thanks! I will check it the next time the system dead-freezes and/or crashed. Hopefully this can be resolved.
The dead-freeze just happend again. I looked through syslog, dmesg, kern.log and the journal. None of those contain any logs close to the date/time of the freeze.. Not sure what to do here. Any idea @xanmod?
@cj0nes: Are you using BTRFS by any chance?
@xanmod:
I am quite certain that the issue has something to do with either BTRFS specifically or the filesystem in general. The freeze happend exactly as I was saving a text file. I just opened up that file again and it suddenly is completely empty. It was not empty originally, then I added a line of text, saved it, then the PC froze, I hard-rebooted it (via the reset button on the case) and now the file is completely empty.
If this cannot be resolved asap, I have to leave this kernel because data loss is obviously the worst that can happen and unfortunately did happen.
Well, apparently much more than a single file has been corrupted. It broke multiple applications (they won't start anymore), several Wine applications (including Office 365). Definitely have to move away from this kernel for now.
@cj0nes: Are you using BTRFS by any chance?
Yes, I am actually. Is there any particular output I can share that would help?
Yeah, that pretty much confirms my suspicion that the issue has something to do with BTRFS. I do not experience this issues when using the stock kernel, so there is most certainly something wrong with the BTRFS implementation in the Xanmod kernel.
Hopefully @xanmod will be able to sort this out. For now I have switched back to the stock kernel to avoid any further data loss.
@Shadow505, I fell back to 5.11.12-rt11-xanmod1, if that's any help for narrowing down what the issue could be in the newer Xanmod kernel.
