Public bug reported: == Comment: #0 - Hari Krishna Bathini <hbath...@in.ibm.com> - 2018-01-08 01:06:41 == ---Problem Description--- A default offset of 128MB is enforced for crashkernel by kdump-tools utility overriding the kernel default.
While the kernel default offset for crashkernel is also 128MB, that may change and the right thing to do would be to let the kernel decide on the offset of crashkernel in the default scenario.. Get rid of "@128M" in kdump-tools.cfg file Contact Information = hbath...@in.ibm.com ---uname output--- na Machine Type = na ---Debugger--- A debugger is not configured ---Steps to Reproduce--- # cat /etc/default/grub.d/kdump-tools.cfg GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT crashkernel=2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M@128M" --- The offset is specified via kdump-tools where as the kernel may be the right place to set an offset by default..
