Hi Hillf, * syzbot <syzbot+listbb8340e4e1f8191bee93@xxxxxxxxxxxxxxxxxxxxxxxxx> [700101 02:00]: > <5> 73 Yes general protection fault in serial8250_tx_chars > https://syzkaller.appspot.com/bug?extid=837b8c9032c053262db8 Can you please send your earlier fix [0] to the linux-serial mailing list so it can be applied? Not quite sure what triggers the serial_port_remove().. But let's fix the serial_port_runtime_resume() issue first. Regards, Tony [0] https://groups.google.com/g/syzkaller-bugs/c/m3vOaJRjnMs
