Sorry, I had overseen that I had to install this package too. The kdump was created when the machine got stuck after trying to resume with kernel 5.16.11-lp153.2.g90630c5-default.

Booted with Kernel 5.3.18-150300.59.49-default alt-sysrq-c did not trigger the dump after resume. Generally, the machine did not work properly with that kernel (problems with opening LVM - must vgchange -a y manually and wait a bit, then init 5 manually), so I changed from the very beginning to the almost perfect working Kernel 5.16.9 and following versions up to 5.16.11. -- You are receiving this mail because: You are the assignee for the bug.
