Hi,
Thanks for the detailed bug report.
From the call stack, I think the crash is more likely here:
https://elixir.bootlin.com/linux/v6.6/source/kernel/time/timer.c#L605
Ah, right, sorry about that.
But the timer looks correctly initialized in
https://elixir.bootlin.com/linux/v6.6/source/drivers/gpu/drm/drm_probe_helper.c#L908
So I'm not sure why it fails in this case.
If I revert commit f81bb0ac7872893241319ea82504956676ef02fd
("drm/ast: report connection status on Display Port."), the splat
goes away:

This has happened before when drm_kms_helper_poll_init() was added
to an ast connector_init(), see:
The crash was in the detect() callback for that previous case.
This time it crashes when setting the timer, but they still look very similar, thanks for pointing this.
Right, I thought that since they both added poll_init() calls,
then there was a wrong assumption about what poll_init() was
doing, but see below.
commit 595cb5e0b832a3e100cbbdefef797b0c27bf725a
Author: Kim Phillips <kim.phillips@xxxxxxx>
Date: Thu Oct 21 10:30:06 2021 -0500
Revert "drm/ast: Add detect function support"
I'm willing to test any proposed changes, esp. if it means
not reverting this commit, too, because that will only likely
lead to yet another BUG instance if/when another poll_init() gets
added in the future. Should the FIXME described in
reschedule_output_poll_work() be addressed?
This fixme just change the timer interval from 10s to 1s, so it shouldn't explain this crash.
Ok, since my config has so much debug, it slows things
down a lot, so I thought it could have been related.
Can you test with the attached patch ? I want to see if the detect callback is called, and also make sure the delayed_work struct is properly initialized.
Thanks, and yes, alright, there's more that meets the eye here.
Adding your printks show the values get preserved, but also now
the BUG doesn't trigger.
With my original CPA_DEBUG=y and init_on_free=1, prior to
the BUG reported, this list_del corruption occurs, which
I had thought was unrelated before:
