Hi, I’m running Fedora 42 on a HP Pavilion with kernel 6.14.11-300.fc42.x86_64, with KDE6.4 (it happens on 6.3 as well)
When my laptop goes into suspend it will hard freeze when coming back out. I have run an ssh session from another machine to watch dmesg as it goes down but upon “waking” the session doesn’t come back, it’s not just graphically frozen. I can’t get into another tty.
I have also tried enabling kdump and the output of kdumpctl status is
sudo kdumpctl status
kdump: Kdump is operational
kdump: Notice: Last successful vmcore creation on Thu 19 Jun 11:27:09 BST 2025
The vmcore that is created is just one from kdumpctl test. I am unable to get a crash dump from when I suspend/resume to even start to have a look at it.
Please can someone help as to what else I can try to see where the issue might be. I am not sure exactly when it started unfortunately as I don’t use my laptop all that much, so I couldn’t say on kernel X.xx it was fine for example.
Edit:
Kernel has updated to Linux 6.15.3-200.fc42.x86_64 and the problem persists.
