Public bug reported: == Comment: #0 - Hari Krishna Bathini <[email protected]> - 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..
