Hi Svavar, This looks like a problem that we have seen before on similar platforms, and I'm hoping that the workaround we have already provided will resolve the issue. Please follow these steps and let us know.
First, we will need to update your driver version from 8.0.6 to the latest, which includes the workaround. Please download the e1000-8.0.16 driver from the e1000 sourceforge site. You'll see the driver tarball when you click on the e1000 stable link at https://sourceforge.net/projects/e1000/files/ Extract the tarball tar xvzf e1000-8.0.16.tar.gz Build it cd e1000-8.0.16/src make Install using the new TxDescriptorStep parameter for each of your 3 interfaces to activate the workaround. modprobe e1000 TxDescriptorStep=4,4,4 Bring the interfaces up and retest. Please let me know if you need more detail, and I will be glad to help further. Dave -----Original Message----- From: Svavar Örn Eysteinsson [mailto:sva...@fiton.is] Sent: Thursday, October 01, 2009 4:43 AM To: e1000-devel@lists.sourceforge.net Subject: [E1000-devel] TX Unit hang with Intel Pro/1000 (82541PI) (e1000) driver on Firewall/NAT machine. Help needed Hi. I'm having a very serious trouble with TX Unit Hang on my Firewall/NAT machine that serves 100 pc's and devices and 4 networks. The machine has 1.5GB in RAM, AMD Sempron(tm) Processor 2600+ at 1.6Ghz. The network cards consist of 3 pieces of Intel Pro/1000 GT Desktop Adapters 82541PI (rev 05), and one VIA [Rhine-II] network card. My OS is Fedora 10, with 2.6.27.15-170 KERNEL. My e1000 driver is 8.0.6-NAPI Iptables is 1.4.1.1 To my problem. Every now and then, I get a "TX Unit Hang" on mostly on my ETH1 interface (that is a internal interface) but now these days I'm getting it at my EXTERNAL interface (eth0). When this Tx Unit Hangs comes up. No traffic is generated in or out on my firewall machine. To fix the problem I have to relaunch the Firewall script. Script generated by Fwbuilder. When the script has relaunched all traffic is normal. We also host many WWW servers, and email servers. I' have recently inserted a scheduled cron job to relaunch the firewall script at 1hour basis, but that is not a solution for this problem. Can someone help me out, or give me some information regarding this annoying problem. Thanks in advance. Best regards, Svavar O Reykjavik - Iceland. < Here's my messages.log output > Sep 30 00:33:20 localhost kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Sep 30 00:33:20 localhost kernel: Tx Queue <0> Sep 30 00:33:20 localhost kernel: TDH <c3> Sep 30 00:33:20 localhost kernel: TDT <c3> Sep 30 00:33:20 localhost kernel: next_to_use <c3> Sep 30 00:33:20 localhost kernel: next_to_clean <d7> Sep 30 00:33:20 localhost kernel: buffer_info[next_to_clean] Sep 30 00:33:20 localhost kernel: time_stamp <dae9c1d0> Sep 30 00:33:20 localhost kernel: next_to_watch <d7> Sep 30 00:33:20 localhost kernel: jiffies <dae9cb38> Sep 30 00:33:20 localhost kernel: next_to_watch.status <0> Sep 30 00:33:22 localhost kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Sep 30 00:33:22 localhost kernel: Tx Queue <0> Sep 30 00:33:22 localhost kernel: TDH <c3> Sep 30 00:33:22 localhost kernel: TDT <c3> Sep 30 00:33:22 localhost kernel: next_to_use <c3> Sep 30 00:33:22 localhost kernel: next_to_clean <d7> Sep 30 00:33:22 localhost kernel: buffer_info[next_to_clean] Sep 30 00:33:22 localhost kernel: time_stamp <dae9c1d0> Sep 30 00:33:22 localhost kernel: next_to_watch <d7> Sep 30 00:33:22 localhost kernel: jiffies <dae9d308> Sep 30 00:33:22 localhost kernel: next_to_watch.status <0> Oct 1 11:17:31 localhost kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Oct 1 11:17:31 localhost kernel: Tx Queue <0> Oct 1 11:17:31 localhost kernel: TDH <e2> Oct 1 11:17:31 localhost kernel: TDT <e2> Oct 1 11:17:31 localhost kernel: next_to_use <e2> Oct 1 11:17:31 localhost kernel: next_to_clean <f6> Oct 1 11:17:31 localhost kernel: buffer_info[next_to_clean] Oct 1 11:17:31 localhost kernel: time_stamp <e25de7af> Oct 1 11:17:31 localhost kernel: next_to_watch <f6> Oct 1 11:17:31 localhost kernel: jiffies <e25debb0> Oct 1 11:17:31 localhost kernel: next_to_watch.status <0> Oct 1 11:17:33 localhost kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Oct 1 11:17:33 localhost kernel: Tx Queue <0> Oct 1 11:17:33 localhost kernel: TDH <e2> Oct 1 11:17:33 localhost kernel: TDT <e2> Oct 1 11:17:33 localhost kernel: next_to_use <e2> Oct 1 11:17:33 localhost kernel: next_to_clean <f6> Oct 1 11:17:33 localhost kernel: buffer_info[next_to_clean] Oct 1 11:17:33 localhost kernel: time_stamp <e25de7af> Oct 1 11:17:33 localhost kernel: next_to_watch <f6> Oct 1 11:17:33 localhost kernel: jiffies <e25df380> Oct 1 11:17:33 localhost kernel: next_to_watch.status <0> Oct 1 11:17:35 localhost kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Oct 1 11:17:35 localhost kernel: Tx Queue <0> Oct 1 11:17:35 localhost kernel: TDH <e2> Oct 1 11:17:35 localhost kernel: TDT <e2> Oct 1 11:17:35 localhost kernel: next_to_use <e2> Oct 1 11:17:35 localhost kernel: next_to_clean <f6> Oct 1 11:17:35 localhost kernel: buffer_info[next_to_clean] Oct 1 11:17:35 localhost kernel: time_stamp <e25de7af> Oct 1 11:17:35 localhost kernel: next_to_watch <f6> Oct 1 11:17:35 localhost kernel: jiffies <e25dfb50> Oct 1 11:17:35 localhost kernel: next_to_watch.status <0> Oct 1 11:17:37 localhost kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Oct 1 11:17:37 localhost kernel: Tx Queue <0> Oct 1 11:17:37 localhost kernel: TDH <e2> Oct 1 11:17:37 localhost kernel: TDT <e2> Oct 1 11:17:37 localhost kernel: next_to_use <e2> Oct 1 11:17:37 localhost kernel: next_to_clean <f6> Oct 1 11:17:37 localhost kernel: buffer_info[next_to_clean] Oct 1 11:17:37 localhost kernel: time_stamp <e25de7af> Oct 1 11:17:37 localhost kernel: next_to_watch <f6> Oct 1 11:17:37 localhost kernel: jiffies <e25e0320> Oct 1 11:17:37 localhost kernel: next_to_watch.status <0> Oct 1 11:17:39 localhost kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Oct 1 11:17:39 localhost kernel: Tx Queue <0> Oct 1 11:17:39 localhost kernel: TDH <e2> Oct 1 11:17:39 localhost kernel: TDT <e2> Oct 1 11:17:39 localhost kernel: next_to_use <e2> Oct 1 11:17:39 localhost kernel: next_to_clean <f6> Oct 1 11:17:39 localhost kernel: buffer_info[next_to_clean] Oct 1 11:17:39 localhost kernel: time_stamp <e25de7af> Oct 1 11:17:39 localhost kernel: next_to_watch <f6> Oct 1 11:17:39 localhost kernel: jiffies <e25e0af0> Oct 1 11:17:39 localhost kernel: next_to_watch.status <0> lspci shows : 00:00.0 Host bridge: VIA Technologies, Inc.
