We found machines with >32 E820 memory map entries, where Xen fails to boot (but Linux does boot fine). The native Linux (both x86 and x86_86) already has: #define E820MAX 128 /* number of entries in E820MAP */ Signed-off-by: Jun Nakajima <jun.nakajima@xxxxxxxxx> Jun --- Intel Open Source Technology Center -- diff -r 3bb1857981e6 -r 51e9c0c806b2 xen/include/asm-x86/e820.h --- a/xen/include/asm-x86/e820.h Tue Aug 16 19:38:22 2005 +++ b/xen/include/asm-x86/e820.h Wed Aug 17 17:00:29 2005 @@ -3,7 +3,7 @@ #include <asm/page.h> -#define E820MAX 32 +#define E820MAX 128 #define E820_RAM 1 #define E820_RESERVED 2
