NACK. The fix is incorrect and just invalidates the case statement in general.
The TX hang message really doesn't tell you anything and it would be more useful to see the full logs. We'll need a lot more information to debug this issue. I would suggest filing the issue on sourceforge with all the usual full info: OS version Kernel version CPU information (model number and speed) Motherboard information (model number) Memory (how much, what speed, what size) dmesg ethtool -S ethX ethtool -i ethX cat /proc/interrupts cat /var/log/messages lspci -vvv Todd Fujinaka Software Application Engineer Networking Division (ND) Intel Corporation todd.fujin...@intel.com (503) 712-4565 -----Original Message----- From: Tony Battersby [mailto:to...@cybernetics.com] Sent: Wednesday, January 07, 2015 6:59 AM To: e1000-devel@lists.sourceforge.net Subject: [E1000-devel] [PATCH] igb: fix Tx Unit Hang on 82576 with RSS > 1 On my Supermicro X8DTH-6F motherboard, the onboard 82576 ethernet ports are completely inoperable with the latest igb from sourceforge when using RSS > 1.
