![]() If serial console wake-up is enabled ("echo enabled >
/sys/.../ttySC0/power/wakeup"), and any serial input is received while
the system is suspended, serial port input no longer works after system
resume.
Note that:
1) The system can still be woken up using the serial console,
2) Serial port input keeps working if the system is woken up in some
other way (e.g. Wake-on-LAN or gpio-keys), and no serial input was
received while suspended.
To fix this, replace SET_LATE_SYSTEM_SLEEP_PM_OPS() by
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS(), as the callbacks installed by the
former happen too early resp. late in the suspend resp. resume process.
