Hi Dave, hi co, I noticed a behaviour change regarding System.map handling regarding newer kernel like 4.14+ As a example: below command works: crash -d 1 vmlinux-4.14.43-1-pserver ps402a-30-dump.201806041421 > good.txt below command report error: crash -d 1 vmlinux-4.14.43-1-pserver System.map-4.14.43-1-pserver ps402a-30-dump.201806041421 > bad.txt crash: page excluded: kernel virtual address: ffffffff82237f18 type: "page_offset_base" When compare the difference between good.txt and bad.txt, I noticed following only in good.txt: KASLR: _stext from vmlinux-4.14.43-1-pserver: ffffffff81000000 _stext from vmcoreinfo: ffffffff9e000000 relocate: 1d000000 (464MB) I tried also on latest Ubuntu 1804, crash reports same error when run with System.map file. Is this expected?
