Have a read of http://osdir.com/ml/general/2013-05/msg46973.html and see 
if this is the same issue (sorry for not linking directly to Xen, Google 
seems to link to the wrong message when I follow its links).
If it is the same issue, then a patch has been submitted and accepted 
which I believe is destined for 4.3. Also, there was an issue around the 
regex stuff which got cleared up by a previous patch that I traced back 
to yaji (maybe!). I don't know when the other fix came in, so you may 
need to go to 4.22 to apply the linked patch.
