Can you confirm the appropriate test kernel was booted with 'uname -a'? You should see the text 'lp1758206' in the kernel name. Also, could there be more the the three patches required that were posted to the description: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=04b9c96eae72d862726f2f4bfcec2078240c33c5 ("powerpc/crash: Remove the test for cpu_online in the IPI callback") https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4145f358644b970fcff293c09fdcc7939e8527d2 ("powernv/kdump: Fix cases where the kdump kernel can get HMI's") https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=910961754572a2f4c83ad7e610d180 ("powerpc/kdump: Fix powernv build break when KEXEC_CORE=n") -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1758206 Title: Ubuntu 18.04 [ WSP DD2.2 with stop4 and stop5 enabled ]: kdump fails to capture dump when smt=2 or off.

I built a Bionic test kernel with the three commits mentioned in the bug description. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1758206 Can you test this kernel and see if it resolves this bug? Note, to test this kernel, you need to install both the linux-image and linux-image-extra .deb packages.
