That's why we get the strangely aligned memory sections. The section starting at 0 is for the kdump kernel, the bit at 0x77c0 covers some firmware that's allocated there by the first kernel. I can still give you a .config and log if you want it, but not 'til tomorrow morning. > Anyhow, will take a look and see if we can avoid iterating over the area > to find it. Yeah it's a bit nasty having the loop. I figure on most configs it'll pop on the first iteration, but still. cheers -- Michael Ellerman IBM OzLabs wwweb: http://michael.ellerman.id.au phone: +61 2 6212 1183 (tie line 70 21183) We do not inherit the earth from our ancestors, we borrow it from our children. - S.M.A.R.T Person
