| − | A variety of [[Ethernet]] controllers is integrated into almost all models starting with the introduction of the A, T and X series.
| |
| − | | |

| |
| − | Note: DO NOT(!!!) use the "irqpoll" boot parameter. This causes the network card to lose it's irq, and makes any stability of the network connection impossible.
| |
| − | Note: There is a [[Problem with e1000: Open issue with latency|known issue]] with the e1000, t60/t60p and the 2.6.17 kernel. It is unconfirmed if this issue effects other configurations.<br>
| |
| − | Note: This chip supports Auto-MDIX, meaning you will never need a crossover ethernet cable.<br>
| |
| − | Note: The first signs of explicit support for this chip in 2.6 kernels is with 2.6.12-rc2.<br>
| |
| − | Note: Red Hat Enterprise Linux 3.0 (2.4 kernel based) begins 82573L support with Update 7.<br>
| |
| − | Note: Some users report issues: [[Problem_with_e1000:_EEPROM_Checksum_Is_Not_Valid]]. This issue stands behind the symptom, that the intel controller 82573L will only work, if a network cable is attached at boot time (seen at X60 running with ubuntu).<br>
| |
| − | Note: Some users have reported [http://forum.thinkpads.com/viewtopic.php?p=201279&sid=787564d7cf9de5d7d76b0cb312a98c61 latency problems] with e1000 driver. It seems, that [http://agenda.clustermonkey.net/index.php/Tuning_Intel_e1000_NICs switching off Interupt Throttle Rate (ITR)] helps. <br>

| − | Note: [http://support.intel.com/support/network/sb/CS-009209.htm Additional configuration options from Intel]<br/>
| |
| − | Note: Another possibility is to use "RxIntDelay=5".<br/>

| − | Note: How to repair a destroyed eeprom because of the e1000 Kernel bug (Kernel 2.6.27) -> [http://tournament.de/howtos/x200_pxe_e05.html link PXE-E05]
| |
| − | | |
| − | For Gentoo users - compile e1000 as a kernel module and add 'options e1000 InterruptThrottleRate=0,0' to /etc/modules.d/e1000
| |
| − | | |
| − | I had serious performance problems on Ubuntu Edgy (ca. 400 kb/s File transfer rate).
| |
| − | I compiled version e1000-7.3.20 from http://sourceforge.net/projects/e1000/ and this solved my problem.
| |
| − | All other hints above did not improve the file transfer performance (they did improve the ping latency) for me.

| |
| − | * {{Z60m}}, {{Z60t}}
| |
| − | * {{Z61m}}, {{Z61p}}
| |
| − | | |
| − | Note: There are some problems with the driver since kernel 2.6.17 (at least on a Z61p, Z61m). After an ifdown && ifup it doesn't work anymore. A possible workaround is to build the tg3-driver as a module and reload it when this problem occours. (Adding ''pre-up modprobe tg3'' and ''post-down rmmod tg3'' to the corresponding section in /etc/network/interfaces works fine.) Rebooting the machine would also be possible.
| |
| − | This is fixed in kernel 2.6.19-rc5.
| |
| − | | |
| − | The T43 with a stock Linux 2.6.18.1 kernel does not have any problems.
