i have been experiencing issues with a server with SLES 12 at reboot, where the GUI does not seem to start and the machine goes to emergency mode.  
Once in emergency mode, i am left with the option of rebooting the machine with the installation dvd and doing a emergency repair. Then booting it again and the system manages to go into the GUI.  
when looking for the possible problems i have seen the following on the screen:

Firmware Bug: the BIOS has corrupted hw-PMU (MSR 30d is 330)  
tsc: Fast TSC Calibration failed

Please provide suggestions.

Hi  
Is this the same server with the sda2 full?

If not, what files systems in use, it may just need fsck of the  
filesystem, else if running btrfs you should be able to boot a snapshot.

no, this is not the same server with sda2 full.  
i need to do fsck on which drive or partition?  
my fdisk -l is of the following type:

device  
/dev/sda1 - type Linux swap/Solaris  
/dev/sda2 - type Linux and is the boot partition  
/dev/sda3 - type Linux  
/dev/sdb4 - type GPT  
/dev/sdc1 - type W95 FAT32

Hi  
I would guess it’s sda3 it will identify the filesystem;

```auto
fsck /dev/sda3
```

However are sdb4 and sdc1 mentioned in fstab or run the following  
command to see?

```auto
lsblk
```
