I'm not suggesting you to keep using/maintaining such a kernel, it's a
debugging data point to prove whether the MST fixes I'm talking about
helped. If they help perhaps Canonical can do the backport.
Aaron can also potentially give you some test kernels if you can't
compile.
> That leaves only (2). Does this DRM debug enabling have an impact on

long periods, so it cannot disturb my work.
It will fill up your logs (and thus your disk) leaving it on. From your
description ("anytime I set an application in fullscreen mode") I was
under the impression this was easy to reproduce (IE just full screen an
app with the monitors connected). Is that not the case?
If it's that easy to reproduce maybe Aaron can try too.
> If there's a kernel from 25.04 (assuming it's 6.13?) that could be
rebuilt and signed for 24.10, that may be also a way
Not that I can tell.

Title:
kernel panic when setting application in fullscreen
Status in linux package in Ubuntu:
New
Bug description:
Since 24.10, on amdgpu device (AMD Ryzen 7 PRO 5850U), anytime I set
an application in fullscreen mode (video player, firefox, signal etc.)
I end up with this crash.
It seems to only reproduce when I have my two 4K screens connected to
the USB-C ThinkPad Thunderbolt station. Laptop screen is disabled in
that setup. I dont reproduce when only on the laptop screen.
