dmesg output
Hello
I am running Debian SID on my Microsoft Surface Laptop 5 using the Surface
specific kernel from https://github.com/linux-surface/linux-surface. After
suspending the machine by closing the lid, it has trouble with waking up when I
re-open the lid (note: this is not an issue if I suspend the machine by other
means, for example using the GNOME power menu):
- Once I open the lid, the keyboard light will turn on, but the screen usually
remains black (with some rare and apparently erratic exceptions, when the
screen turns on fine).
- If I wait a few seconds until the keyboard lights turn off again and then
press any key (not the power button), the screen usually turns on and the
machine works as expected (with some rare and apparently erratic exceptions,
when the screen remains black).
- Running `sudo dmesg` right after such a lid-close/suspend/lid-open/wake-up
cycle produced the output in the attachment. Note that the ACPI error `Could
not disable RealTimeClock events` also occurs at boot (not shown in the
attachment).
I have already reported and discussed this issue with the maintainer of the
Surface specific kernel at
https://github.com/linux-surface/linux-surface/issues/1010, who concluded that
this issue should be reported upstream (here).
