Subject: Re: [PATCH 1/1] r8169: reset IntrStatus after chip reset

> Original comment (Karsten):
> On a MSI MS-6702E mainboard, when in rtl8169_init_one() for the first time
> after BIOS has run, IntrStatus reads 5 after chip has been reset.
> IntrStatus should equal 0 there, so patch changes IntrStatus reset to happen
> after chip reset instead of before.
