I've done now the rebased/splitted patches, was slow at verifying/reviewing 
things but I think it's now good. In my previous patch to me I saw that was 
doing some uneeded things, also was better to reuse patch_stac92hd71bxx 
instead of splitting 4port/5port support/differences away. I removed the pin 
configs for HP models too, it may be wrong/uneeded or cause problems like in 
this case. Find attached now three patches with splitted fixes/enhancements, 
but nothing that will help with the problem here unfortunately, I thought the 
previous patch with pin configs could help.
