Re: pci config space bit change on the host bridge after resume

- 00: 86 80 40 33 06 01 90 30 03 00 00 06 00 00 00 00
+ 00: 86 80 40 33 06 01 90 20 03 00 00 06 00 00 00 00

byte 7 bit 4 cleared -- that is the Received Target Abort bit
in the PCI status register.  It is probably set as a result
of us reading from a slot that isn't present.
As the status register is write-1-to clear,
you can't bring this bit back by writing to it even if you wanted to.

I think this address is incorrect anyway, this will write bytes 8 an 9
when you wanted to write byte 7, yes?
 
$SETPCI -s $DEV 07.b=0x03
