 The patch doesn't appear to help at all, my last two runs failed in 4
 and 7.5 minutes, so potentially worse than it was.
 
 The short cable fix messages are different now:
 
 Feb 19 01:26:56 oldvoi kernel: sis0: Applying short cable fix (reg=f)
 Feb 19 01:26:56 oldvoi kernel: sis0: Applying short cable fix (reg=e)
 Feb 19 01:26:56 oldvoi last message repeated 2 times
 Feb 19 01:33:37 oldvoi kernel: sis0: Applying short cable fix (reg=ee)
 Feb 19 01:34:29 oldvoi kernel: sis0: Applying short cable fix (reg=e)
 Feb 19 01:35:28 oldvoi kernel: sis0: Applying short cable fix (reg=10)
 Feb 19 01:37:32 oldvoi kernel: sis0: Applying short cable fix (reg=e)
 Feb 19 01:39:03 oldvoi kernel: sis0: Applying short cable fix (reg=ec)
 Feb 19 01:40:02 oldvoi kernel: sis0: Applying short cable fix (reg=f)
 Feb 19 01:40:16 oldvoi kernel: sis0: Applying short cable fix (reg=ee)
 Feb 19 01:40:28 oldvoi kernel: sis0: Applying short cable fix (reg=ec)
 
 Note the lack of bursty several-in-a-second and the changing reg=
 values.  Compared with pre-patch:
 
 Feb 16 15:23:50 oldvoi kernel: sis0: Applying short cable fix (reg=e8)
 Feb 16 15:24:27 oldvoi last message repeated 2 times
 Feb 16 15:26:20 oldvoi last message repeated 11 times
 Feb 16 15:34:01 oldvoi last message repeated 26 times
