Hi,
I recently noticed that on current kernels I lose video output from
my Blackbird's AST2500 BMC after a reboot, which makes it difficult to
boot the system again (the video output will come on only after Linux
is booted again).
With Linux 6.6 and earlier, there is no problem rebooting, everything
is fine.
I bisected to this commit:
ce3d99c8349584bc0fbe1e21918a3ea1155343aa is the first bad commit

drm: Call drm_atomic_helper_shutdown() at shutdown time for misc drivers
This commit does not revert cleanly on 6.14, but I can easily undo
the changes this commit made to the ast driver, and this is enough
to restore working behaviour.
Let me know if you need any more info!
Would you be able to test a patch?
Best regards
Thomas
Thanks,
Nick
