https://bugzilla.novell.com/show_bug.cgi?id=350963 Summary: Intel Gigabit Ethernet e1000 NIC hangs under high network loads Product: openSUSE 10.3 Version: Final Platform: i386 OS/Version: openSUSE 10.3 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: spameman@gmx.net QAContact: qa@suse.de Found By: Customer I noticed that the network gets stuck maybe once per minute if I try to copy gigs of mpeg files from my openSuse 10.3 server to my windows box. Both machines are connected via a gigabit switch. In /var/log/messages "Detected TX Unit Hang Messages" are printed if the problem happens. I'm using a Intel 82541PI Gigabit Ethernet Controller. It is plugged into a ASRock K7VT4APro board. Kernel is 2.6.22.13-0.3-default The following link seams to describe the problem. There is a suggestion to patch the eeprom of the card but the patch only supports 82573 chipsets. http://e1000.sourceforge.net/doku.php?id=known_issues#v_l_e_tx_unit_hang_mes... /var/log/messages Dec 29 20:16:01 leela kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Dec 29 20:16:01 leela kernel: Tx Queue <0> Dec 29 20:16:01 leela kernel: TDH <5e> Dec 29 20:16:01 leela kernel: TDT <b9> Dec 29 20:16:01 leela kernel: next_to_use <b9> Dec 29 20:16:01 leela kernel: next_to_clean <5b> Dec 29 20:16:01 leela kernel: buffer_info[next_to_clean] Dec 29 20:16:01 leela kernel: time_stamp <216b5025> Dec 29 20:16:01 leela kernel: next_to_watch <5f> Dec 29 20:16:01 leela kernel: jiffies <216b5604> Dec 29 20:16:01 leela kernel: next_to_watch.status <0> Dec 29 20:16:03 leela kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Dec 29 20:16:03 leela kernel: Tx Queue <0> Dec 29 20:16:03 leela kernel: TDH <5e> Dec 29 20:16:03 leela kernel: TDT <b9> Dec 29 20:16:03 leela kernel: next_to_use <b9> Dec 29 20:16:03 leela kernel: next_to_clean <5b> Dec 29 20:16:03 leela kernel: buffer_info[next_to_clean] Dec 29 20:16:03 leela kernel: time_stamp <216b5025> Dec 29 20:16:03 leela kernel: next_to_watch <5f> Dec 29 20:16:03 leela kernel: jiffies <216b57f8> Dec 29 20:16:03 leela kernel: next_to_watch.status <0> Dec 29 20:16:04 leela kernel: NETDEV WATCHDOG: eth0: transmit timed out Dec 29 20:16:07 leela kernel: e1000: eth0: e1000_watchdog_task: NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX Dec 29 20:16:50 leela vdr: [1521] changing pids of channel 1153 from 171+171:124=fra:0 to 171+171:124=fra,125=eng:0 Dec 29 20:16:50 leela vdr: [1521] changing caids of channel 1153 from 100 to 0 Dec 29 20:16:50 leela vdr: [1521] changing ca descriptors of channel 1153 Dec 29 20:17:01 leela /usr/sbin/cron[1684]: (root) CMD ( /root/scripts/checkInternet.sh) Dec 29 20:17:05 leela kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Dec 29 20:17:05 leela kernel: Tx Queue <0> Dec 29 20:17:05 leela kernel: TDH <2d> Dec 29 20:17:05 leela kernel: TDT <63> Dec 29 20:17:05 leela kernel: next_to_use <63> Dec 29 20:17:05 leela kernel: next_to_clean <2d> Dec 29 20:17:05 leela kernel: buffer_info[next_to_clean] Dec 29 20:17:05 leela kernel: time_stamp <216b920d> Dec 29 20:17:05 leela kernel: next_to_watch <31> Dec 29 20:17:05 leela kernel: jiffies <216b9484> Dec 29 20:17:05 leela kernel: next_to_watch.status <0> Dec 29 20:17:07 leela kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Dec 29 20:17:07 leela kernel: Tx Queue <0> Dec 29 20:17:07 leela kernel: TDH <2d> Dec 29 20:17:07 leela kernel: TDT <63> Dec 29 20:17:07 leela kernel: next_to_use <63> Dec 29 20:17:07 leela kernel: next_to_clean <2d> Dec 29 20:17:07 leela kernel: buffer_info[next_to_clean] Dec 29 20:17:07 leela kernel: time_stamp <216b920d> Dec 29 20:17:07 leela kernel: next_to_watch <31> Dec 29 20:17:07 leela kernel: jiffies <216b9678> Dec 29 20:17:07 leela kernel: next_to_watch.status <0> Dec 29 20:17:09 leela kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Dec 29 20:17:09 leela kernel: Tx Queue <0> Dec 29 20:17:09 leela kernel: TDH <2d> Dec 29 20:17:09 leela kernel: TDT <63> Dec 29 20:17:09 leela kernel: next_to_use <63> Dec 29 20:17:09 leela kernel: next_to_clean <2d> Dec 29 20:17:09 leela kernel: buffer_info[next_to_clean] Dec 29 20:17:09 leela kernel: time_stamp <216b920d> Dec 29 20:17:09 leela kernel: next_to_watch <31> Dec 29 20:17:09 leela kernel: jiffies <216b986c> Dec 29 20:17:09 leela kernel: next_to_watch.status <0> Dec 29 20:17:11 leela kernel: e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang Dec 29 20:17:11 leela kernel: Tx Queue <0> Dec 29 20:17:11 leela kernel: TDH <2d> Dec 29 20:17:11 leela kernel: TDT <63> Dec 29 20:17:11 leela kernel: next_to_use <63> Dec 29 20:17:11 leela kernel: next_to_clean <2d> Dec 29 20:17:11 leela kernel: buffer_info[next_to_clean] Dec 29 20:17:11 leela kernel: time_stamp <216b920d> Dec 29 20:17:11 leela kernel: next_to_watch <31> Dec 29 20:17:11 leela kernel: jiffies <216b9a60> Dec 29 20:17:11 leela kernel: next_to_watch.status <0> Dec 29 20:17:12 leela kernel: NETDEV WATCHDOG: eth0: transmit timed out Dec 29 20:17:15 leela kernel: e1000: eth0: e1000_watchdog_task: NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX Dec 29 20:17:49 leela dhcpd: DHCPREQUEST for 192.168.10.5 from 00:09:34:14:a4:6b via eth0 Dec 29 20:17:49 leela dhcpd: DHCPACK on 192.168.10.5 to 00:09:34:14:a4:6b via eth0 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
