I tested the mainline kernel v6.8-rc5 without this problem, as I said before, this problem only occurs in 5.4 LTS, to be precise, it can occur from v5.4.217, with CONFIG_RETPOLINE and CONFIG_LIVEPATCH enabled

BTW: The patch for V2 version has been sent out. We can discuss based on that. Thank you!
