I can't necessarily rule that out, however, based on the stack trace you attached, this looks like a software bug. If you want to go further, I recommend following Ted's suggestion and attempt to reproduce with a recent upstream kernel. The most recent stable version as I write this is 6.8.1. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
