Hi, I encounter a case where crashkernel=384M, and kaslr is enabled. During the test, sometimes, the system may fail to reserve region for crash kernel, although there is much free space above 896MB. It is caused by the truncation of the candidate region by kaslr kernel. It raises confusion to the end user that sometimes crashkernel=X works while sometimes fails. So can we have this patch to fix the issue?
