Yes, this issue was fixed with commits:

8b3408f8ee994973869d8ba32c5bf482bc4ddca4 dp83640: free packet queues on remove
f5ff7cd1a84caa9545d952a37ac872ccb73825fb dp83640: use proper function to free transmit time stamping packets
da92b194cc36b5dc1fbd85206aeeffd80bee0c39 net: hold sock reference while processing tx timestamps

These commits also were applied to stable kernels 3.0 and 3.1.

HTH,
