When booting a new non-kdump kernel, we have below failure message: [ 0.004000] DMAR-IR: IRQ remapping was enabled on dmar2 but we are not in kdump mode [ 0.004000] DMAR-IR: Failed to copy IR table for dmar2 from previous kernel [ 0.004000] DMAR-IR: IRQ remapping was enabled on dmar1 but we are not in kdump mode [ 0.004000] DMAR-IR: Failed to copy IR table for dmar1 from previous kernel [ 0.004000] DMAR-IR: IRQ remapping was enabled on dmar0 but we are not in kdump mode [ 0.004000] DMAR-IR: Failed to copy IR table for dmar0 from previous kernel [ 0.004000] DMAR-IR: IRQ remapping was enabled on dmar3 but we are not in kdump mode [ 0.004000] DMAR-IR: Failed to copy IR table for dmar3 from previous kernel For non-kdump case, we no need to copy IR table from previous kernel so it's nonthing actually failed. To be less alarming or misleading, do not print "DMAR-IR: Failed to copy IR table for dmar[0-9] from previous kernel" messages when booting non-kdump kernel.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
