Yes either you can modify in-kernel driver code Or I will provide you the latest e1000e out of tree driver from http://sourceforge.net/projects/e1000/files/ with debug info enabled. -Tushar > > Thanks. > > -Tushar > > > -----Original Message----- > From: Pratyush Anand [mailto:pratyush.an...@st.com] > Sent: Monday, January 09, 2012 8:21 PM > To: Dave, Tushar N > Cc: Greg KH; Pratyush Anand; e1000-devel@lists.sourceforge.net; > net...@vger.kernel.org; Shiraz HASHIM; Deepak SIKRI; Bhavna YADAV; > linux-...@vger.kernel.org; Linux NICS > Subject: Re: Detected Hardware Unit Hang on Intel Wired Ethernet > > On 1/7/2012 12:25 AM, Dave, Tushar N wrote: >> Pratyush, >> >> Sorry I got your name reversed. >> Are you using in-kernel driver or one from Sourceforge. > > I am using in-kernel driver from kernel 2.6.37. > >> Please send me output of ethtool -i ethx. > > root@192.168.1.10:~# ethtool -i eth0 > driver: e1000e > version: 1.2.7-k2 > firmware-version: 5.11-8 > bus-info: 0000:01:00.0 > > Regards > Pratyush > >> >> -Tushar >> >> -----Original Message----- >> From: Pratyush Anand [mailto:pratyush.an...@st.com] >> Sent: Thursday, January 05, 2012 8:25 PM >> To: Dave, Tushar N >> Cc: Greg KH; Pratyush Anand; e1000-devel@lists.sourceforge.net; >> net...@vger.kernel.org; Shiraz HASHIM; Deepak SIKRI; Bhavna YADAV; >> linux-...@vger.kernel.org; Linux NICS >> Subject: Re: Detected Hardware Unit Hang on Intel Wired Ethernet >> >> Thanks Tushar, >> >> On 1/6/2012 5:24 AM, Dave, Tushar N wrote: >>> Anand, >>> >>> Sorry to hear that you have this issue with card.
