To help diagnose the warning/issue, can you share your TB dock/setup information and the steps that you are following? Also it would be helpful if you can provide logs with dynamic debugging enabled for thunderbolt. I am not able to reproduce the issue at my end, so the above information would be really helpful to look into the issue while I continue checking on my end. From the warning it appears that the tunnels are invalid from the stack trace in the logs. > > On 1/29/26 17:39, Kenneth Crudup wrote: >> >>>> The issue I'm trying to chase down (and not sure if any of this will >>>> help with this, I wonder if it's really BIOS/EC related) is often times >>>> that after a suspend (or hibernate, but I use "suspend then hibernate", >>>> which I think does both and chooses which to use upon resume) and then >>>> connect to a different dock (or setup) from the one I'd suspended with, >>>> sometimes I have to unplug/replug my TB cable, otherwise I either get no >>>> recognition of my new display setup (and sometimes TB devices) or it'll >>>> try and use the same monitor resolution of the previously-connected >>>> monitor (as if the TB subsystem doesn't recognize things have changed). >> >> On 1/29/26 15:13, Katiyar, Pooja wrote: >> >>> Below is the patch series that addresses mentioned issue.
