Certainly not. The problem is the soft lockup watchdog tends to produce false-positives related to the clock resume vs timer interrupt dependencies that are hard to trace. I used to get those on a regular basis until the timer resume on x86-64 got fixed a month ago or so. Please try the latest -mm and see if it's not fixed there. If not, please file a bug report with bugzilla (with Cc to me).
