Hi, |
2 |
For the first time in a couple of years I had a total hard hang |
3 |
today when a Virtualbox VM was doing some updates to M$ Office. The |
4 |
compute server was completely alive & then completely hung. The mouse |
5 |
wouldn't move, I couldn't switch to the console and I couldn't log in |
6 |
from another machine. I tried Alt-Ctrl-SysRq REISUB but there was no |
7 |
response to that either so I went with a hard reset and did some |
8 |
fsck's to ensure everything was OK. (It was...) After bringing the |
9 |
machine back up I tested that the Magic SysRq worked, and it did, so |
10 |
the hang was hard enough to stop even that. |

|
12 |
My question about this is what's your guess about where the hang |
13 |
occurred? Was it purely in the kernel and I just hit some corner |
14 |
condition that caused it? Or could it be that a hang in the VM could |
15 |
completely bring the machine to a halt such that the kernel never |
16 |
gains control even after waiting 15 minutes? |
17 |
|
18 |
The kernel was gentoo-sources-3.0.4, not the -r1 that came out today. |

Looking forward to all ideas. |
