I recently put together a new server running Ubuntu Server 11.10 and it's all working great except for one little detail. Whenever I run "sudo reboot" everything works fine until I get to the grub page, where it auto-selects ubuntu and then only displays a black screen. There is nothing showing on the screen, and I can't access the server with a keyboard. Neither can I access it over SSH.
If I hold the power button down and force the computer to shut down, it will boot in to Ubuntu normally the next time. This only happens the time I run "sudo reboot", and not the following I start it.
As I said, I can't spawn a terminal on the server, not even if I connect a keyboard. It's like it's frozen. I thought maybe somebody here could help me, because I've been trying to solve this for days.
In case this is helpful, I've got a RAID5 running on the server, but I can't imagine it to be the root of the problem.
EDIT: I forgot to write, but I also have a 64GB Crucial M4 as my system disk, where Ubuntu is installed. The raid is just for storage.
These are the server specifications:
- Motherboard: Asus P8H67-M B3
- CPU: Intel Core i3 2120 3,3GHz
- GPU: Asus GeForce ENGT520
- Memory: Corsair XMS3 DDR3 PC10666/1333MHz CL9 2x4GB
- HDD: 3x Seagate Barracuda Green ST2000DL003 64MB 2TB
Thanks in advance!
