Hey, for Fabian the issues are fixed too. It seems like this bug is somehow correlated with #1116619. But anyways together with the feedback from Kushal im confident enough, that this patch fixes the issue.

Oktober 2026, 23:08 From: Fabian S. To: Hefee Hi, good news. I think it fixed it reliably. I recognized that with the packages from deltaone, only Firefox was crashing. There is also someone talking about it in message 57 from the bugreport #1116619 I linked. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1116619&pow_referer=#57 So I did go back to the standard debian packages. My test setup was docked in, Firefox open, Thunderbird open, KeepassXC open. Then go to standby, undock, wakeup, login. With the standard packages. All three applications crash. Deltaone only Firefox crashes. With your packages I can not get it to crash. All three applications stay open. Even with multiple tries. I did reboots between those tests. Notebook is a Thinkpad L13 2in1 with a Ultra 5 125U. Dockingstation is a Thunderbolt 3 Dock from Lenovo. Do you need something else? We could also ask the people from the Debian bugreport to test these packages. Thank you
