I have a Ubuntu machine which randomly reboots itself:



last reboot
reboot system boot 2.6.32-042stab12 Sat Mar 25 23:48 - 12:42 (11:53)
reboot system boot 2.6.32-042stab12 Wed Mar 22 18:28 - 12:42 (3+17:14)
reboot system boot 2.6.32-042stab12 Sat Mar 18 05:10 - 12:42 (8+06:32)
reboot system boot 2.6.32-042stab12 Thu Mar 16 13:52 - 12:42 (9+21:49)
reboot system boot 2.6.32-042stab12 Thu Mar 16 09:50 - 13:52 (04:02)


I am trying to figure out why and stop it. I pasted the logs to pastebin here.



I am not doing these reboots. Also, it seems like there is nothing going on (like a crash, etc.) which would cause the server to reboot.






ubuntu reboot

    There's nothing in the logs. Is it a multiuser system and someone else reboots it?

  • did you deploy the unattended-updates service and allow it to reboot after updates if it was required by an update?

Have you checked /proc/sys/kernel/panic? If it's value is 1 then server will immediately reboot on panic. Bad drivers can cause kernel panic.



If it's not panic, check last issue of reboot, maybe overheating is the issue.



last reboot

            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...
