Can you post an lsmod and the complete dmesg? Softlockups are caused by someone holding interrupts disabled for too long (which can be caused by either a long delay in a critical section, or a deadlock on a spinlock), so they are quite hard to debug without all the info other than the "soft lockup detected" message.
