From: Francois Romieu <romieu@fr.zoreil.com> Date: Thu, 2 Apr 2009 00:09:41 +0200 > 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. > > Remark (Francois): > Assuming that the loglevel of the driver is increased above NETIF_MSG_INTR, > the bug reveals itself with a typical "interrupt 0025 in poll" message > at startup. In retrospect, the message should had been read as an hint of > an unexpected hardware state several months ago :o( > > Fixes (at least part of) https://bugzilla.redhat.com/show_bug.cgi?id=460747 > > Signed-off-by: Karsten Wiese <fzu@wemgehoertderstaat.de> > Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> > Tested-by: Josep <josep.puigdemont@gmail.com> Applied, thanks. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
