[PATCH printk v1 0/1] Fix reported suspend failures

Posted by John Ogness 2 months, 4 weeks ago

Hi,

There have been multiple reports [0][1] (+ 2 offlist) of suspend
failing when NBCON console drivers are in use. With the help of
NXP and NVIDIA we were able to isolate the problem and verify
the fix.

The first NBCON drivers appeared in 6.13, so currently there is
no LTS kernel that requires this series. But it should go into
6.17.x and 6.18.
