Ok.
Also to point out that when it goes to sleep, regardless of dim or blank, will drop the
wifi connections. However, getting out of sleep will eventually (in about a minute)
reconnect.
So SLEPP is equivalent to suspend, disregarding DCON/screen state.

hi yioryos --
thanks for the detailed descriptions.
debugging and drawing conclusions about suspend/resume
problems is pretty hard without a serial connection.
i'll
try and stress an OS13 a little more, and see if i can't
reproduce your symptoms. others with serial ports
are
welcome/encouraged to try as well. ;-)

okay -- this is definitely a kernel issue then. i
think i thought
we'd gotten past all the bad ones, but i guess not.

hard freezes are certainly harder to diagnose.
