Lion locks up computer

[xstux]

Twice in the past 24 hours my iMac has locked up. It starts with the internet dropping and then the apps using the internet start to lock up, not even allowing Force Quit. Eventually everything locks up. The only solution has been to hit the power off button. Anyone else having this problem?

I've been running Lion since release day but have had this problem twice now.

Lion locks up

I've had the same thing happen twice today. I think both times I was starting to view something on Youtube. The only way out was to turn off the computer. Anyone?

Yes. Seems to be related to the Wi-Fi issues with Lion. Happened to me today after my Wi-Fi dropped out (yet again). I have a suspicion that it's related to Time Machine backups.

I've had the same problem a few times, but I'm not really sure what exactly I was doing or what I had running when it happened.
