Andi Kleen ac71d12c99 [PATCH] x86_64: Avoid EBDA area in early boot allocator ... Based on analysis&patch from Robert Hentosch Observed on a Dell PE6850 with 16GB The problem occurs very early on, when the kernel allocates space for the temporary memory map called bootmap. The bootmap overlaps the EBDA region. EBDA region is not historically reserved in the e820 mapping. When the bootmap is freed it marks the EBDA region as usable. If you notice in setup.c there is already code to work around the EBDA in reserve_ebda_region(), this check however occurs after the bootmap is allocated and doesn't prevent the bootmap from using this range. AK: I redid the original patch. Thanks also to Jan Beulich for spotting some mistakes.
