Re: kswapd 0 tainted

Hi adam2508,

I seem to be having a similar problem. I have been running arch now for a month and don't ever want another distro but these last few days my system freezes up leaving me with a black screen and similar output as you listed. The only thing I can do is a hard reset witch I really don't want to do too often.
I'm running gnome and I wonder why the log shows "kswap0 tainted" or is this not KDE related?
I wonder if you have already found a solution as I really don't have a clue. Where do I find the logs I need?

Cheers for any reply from anyone.

Re: kswapd 0 tainted

adam2508, please use code-tags when pasting logs, code or configs.

billy-bones: kswap stands for kernel swap, not kde. All the logs are in /var/log/
