I just upgraded my Ubuntu from 12.10 to 13.04. I use Dell Studio 1558 laptop. After upgrade my system keeps freezing randomly. One it freezes after 3 minutes, once after 1 minute and so on... When it freezes I see all on my screen, but frozen. There is no errors, nothing.on 12.10 system works fine, even more than week. Now it stops and I see screenshot like on my desktop.
Any ideas what to do? If only I could give any logs, but I get nothing.
On Gnome I get freeze with error like on the screen attached. I haven't found any solution for that. REISUB method doesn't work here.
EDIT:
The problem was kernel delivered with 13.04. I've installed 3.9 (rc8) and problem is gone:) But now, there is 3.9 release (link)
Hope that helped you.
