    Please calm down; I cleared all the comments that don't have anything to do with the actual question. I don't know where you got the impression that you can't answer comments like "have you tried running a RAM test", but you can and it'd be a good start to diagnosing the problem

Six years ago I had similar problem with my Fedora server. The kernel messages:



*BAD*gran_size...


can have three basic reasons:



  • corrupted physical memory

  • corrupted BIOS

  • wrong MTRR size

I have solved the problem by enabling MTRR sanitizer, read my post (I'm melal on Fedora forum) and another post below it.



Additionally read this, to understand what the messages *BAD*gran_size... mean.

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
