Thanks for you reply. (Un)fortunately, due to linux keeps updating, I can't reproduce this panic on latest mainline linux master branch now. The HEAD commit is 7ddb58cb0eca. From 8bb7eca972ad (v5.15) to 7ddb58cb0eca (v5.15+), there're many changes, I can't sure which commit fixes this bug, or hide it= ? Do you know if there was a known issue about this has been fixed? Thanks, Zorro --=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.=
