Re: [BUG][2.5.64bk4] Weird problem with 2 PCs

[Shawn Starr]

Can't be, everything is grounded. If i disconnect the serial and reboot the 
A7M266-D it doesn't hang the IBM. I can only suspect the serial ground pin is 
bad.  I will tomorrow try 2.4.2x and see if this occurs. If it does NOT. Then 
we have a problem here and finding it is going to be tough :-(
