https://bugzilla.kernel.org/show_bug.cgi?id=218356 --- Comment #2 from yilei (1016309222@xxxxxx) --- Thank you very much for your reply. I have tested the firmware of buildroot and its kernel version is 4.19.225. This version should not have this issue, but I am currently using the firmware of friendlyWrt and its kernel version is 5.10.110. This version must have this issue. I suspect that buildroot has any patches that have already fixed this issue. Should I consult with the official friendlyWrt? -- You may reply to this email to add a comment.
