Not sure why xattrs->rb_root would be pointing there, this should have been initialized to null.

Thank you, I've done as recommended, but am currently rocking 6.7.7-1-default without issue. Will update if I get anything. Regards -- You are receiving this mail because: You are the assignee for the bug.

I think upstream commit 4207b556e62f ("kernfs: RCU protect kernfs_nodes and avoid kernfs_idr_lock in kernfs_find_and_get_node_by_id()") fixes this issue, and this was backported to v6.8.6 which is now available in TW.

Could you please give it a try and see if this is still reproducible?

I am quite confident this indeed fixes it. Timeframe is only ~24hrs, but I've observed the signs of the underlying state changes that would've previously crashed it, ie corresponding journalctl entries, software and physical battery indicators, fan powercurve changes, go by uneventfully(for a lack of a better word).

Curious if the other person that had filed an issue is using the proprietary NVIDIA driver. PS Since I had no CUDA to do work, I decided to play a game which, in recent weeks, used to result in an outright restart without any log entries/stack traces/kdumps within minutes of it starting up. This time it didn't, and it ran for hours, which points to the nvidia driver being the cause.. -- You are receiving this mail because: You are the assignee for the bug.
