Hello everyone Last night something weird happened. I was locally on my Debian GNU/Linux machine, doing some chatting, whilst suddenly the whole system seemed to get into an unusable state.
I could still switch VTs, but could not login on any of them. Funnily was I able to login remotely, though. Today, I noticed the following (rather long) dump in /var/log/syslog. It doesn't look like a usual Oops, so I am unsure what caused this. Does anyone have a clue what was going on?? Thanks. Okay, here follows the dump: Feb 3 02:08:12 host kernel: Feb 3 02:08:12 host kernel: free sibling Feb 3 02:08:12 host kernel: task PC stack pid father child younger older Feb 3 02:08:12 host kernel:
