When Ubuntu freezes
Scribbled on Saturday, June 14th, 2008What to do if your system is not responding and gone into eternal freeze. You might be tempted to press the restart button on the CPU cabinet or will turn off the UPS.
The easiest trick is to directly communicate with the Kernel via /proc filesystem.
- Press Alt + SysRq/Prt Scr key and type REISUB
It will safely restart your PC with no loss of data.
What if you wanted to shut down the PC
- Press Alt + SysRq/Prt Scr key and then type REISUO
Explanation:
- R tries to communicate with Keyboard directly without the need of X window system
- E tries to end processes by giving them stop/terminate signal (SIGTERM), its a respectful request
- I this is for SOB processes which don’t listen to the kernel, they are killed (SIGKILL) to free the resource locks, thou shalt die who didn’t heed
- S to write the cached changes to the filesystem, so that data is proof written to the disk and poses no data loss
- U now its the time to unmount the filesystems and remount them as read only
- B restarts the sytem
- O turn off/Shut down the system
So next time keep this little handy trick to show some mercy to your system and valuable data.
