This affects any kernel later than 4.19 actually. [Test case] Crash a system with kdump-tools installed and enabled, by using the following sequence. Verify the created dumps are compressed by using file. This is the same test as the autopkgtest for makedumpfile. echo 1 | sudo tee /proc/sys/kernel/sysrq echo c | sudo tee /proc/sysrq-trigger [Regression potential] This is a small fix and should only impact ppc64el. Older kernels should still work, and should be tested.
