to\nhandle kernel paging request at virtual address\" about ten seconds after\nunloading the driver. This happens on uart_hangup() calling\nuart_change_pm().\n\nTurns out commit 04e82793f068 (\"serial: 8250: Reinit port->pm on port\nspecific driver unbind\") was only a partial fix. If the hardware specific\ndriver has initialized port->pm function, we need to clear port->pm too.\nJust reinitializing port->ops does not do this. Otherwise serial8250_pm()\nwill call port->pm() instead of serial8250_do_pm()."}], "lastModified": "2026-08-04T11:16:37.423", "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
