This bug may be a duplicate of #123223. Very same behaviour, as I had the same problem also when browsing with Firefox but on a 2.6.22-13 kernel.
This may show that the bug is older than 2.6.22. -- BUG: soft lockup detected on CPU#0 (and other bugs) while browsing on the net https://bugs.launchpad.net/bugs/123243 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
