 Hmmm, sorry, but are you sure nothing else changed 
 on your system ?
 
 There has been no change to the driver code between
 January 5th and April 20th, and that latter one did
 only change some casts for formal correctnes, but 
 did most likely not result in any changes in the 
 binary being created ...
 
 Does a kernel built from sources before April 18th
 continue to run reliably ?
 
 Did you try with a later kernel ? (I just built a new
 kernel, which doesn't seem to suffer from the problem
 you describe ...)
