I have found a work around. After implementing the suggestion by Aspera (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/656745/comments/26), the frequency of freezing has reduced a bit...
Statistically I could see that if start the system on AC and put it on battery after booting, I can avoid freezing. I dont know understand the technical aspects, but this seems to be a promising solution. Can somebody please explain me the logic? -- VInay -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/656745 Title: notebook always crashes if on battery (dell vostro 3700 and others) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
