Date: Wed, 4 Jan 2012 16:31:36 +0530 From: Pratyush Anand <pratyush.anand@...com> To: Pratyush Anand <pratyush.anand@...il.com> Cc: "e1000-devel@...ts.sourceforge.net" <e1000-devel@...ts.sourceforge.net>, "netdev@...r.kernel.org" <netdev@...r.kernel.org>, Shiraz HASHIM <shiraz.hashim@...com>, Deepak SIKRI <deepak.sikri@...com>, Bhavna YADAV <bhavna.yadav@...com>, <linux-pci@...r.kernel.org> Subject: Re: Detected Hardware Unit Hang on Intel Wired Ethernet Adding PCI mailing list too, as problem is coming only when MSI is enabled. If I connect an PCIe analyzer, I see that at the time of issue MRd(64) for 32 words has been issued with a wrong 64 bit address from ethernet card to my RC. In the normal course it always issues MRd(32) only.
