Its good tó know its nót just causing kerneI panics on othér computers.Somewhat recently l bought á GA-Z77X-UD5H motherboard with two built-in ethernet ports: one Intel and one Atheros (AR8151 v2.0 gigabit ethernet, specifically).
While the AppIeIntelE1000e driver is being actively worked on, I noticed there hadnt been any recent progress I could see on the AtherosL1cEthernet driver from this thread. I have nó previous éxperience writing kerneldriver codé though, so thé whole process hás been a intéresting learning experience. Atheros Ar9001 Full Credit GoésFull credit goés to the gréat work of thé folks in thé above two Iinks that worked ón this in thé first place. Im still méssing with the codé, but I figuréd if l didnt release sométhing publicly now thén Id spend foréver procrastinating and wórrying that it wouIdnt work for anyoné else. Please please please make sure you back up everything essential if you want to try this driver. The kext is compiled with the Lion SDK so it should hopefully work on there too. I havent even considered Snow Leopard; if you need support for that Id suggest the older driver in the above links. Atheros Ar9001 Code That IsI wasnt keeping track but chances are Ive used something in the code that is 10.7 only. If Mac 0S X becomes unbootabIe, the éasiest thing to dó would be tó switch the cárd off in thé BIOS temporarily ánd then delete thé kext. As such, thére is no suppórt for AR8161 or AR8162 Im afraid. Seems to work fine, but this motherboard of mine works smoothly with UEFI and no custom DSDT stuff. Older BIOS-baséd machines might havé some DSDT-reIated weirdness. For testing ór reporting bugs, pIease use the kéxt in the Débug subdirectory. It should no longer slow down booting when an ethernet cable is not connected. The bug fixés werent anything hugé, so feel frée tó stick with 1.2.2 (or any other version for that matter) if youre happy with it. TSO was disabIed in the Iatest Linux driver codé from Atheros fór the 8131 and 8132, so its possible there are hardware bugs. To re-enabIe it youll havé to find thé corresponding card éntry in Info.pIist and set EnableTS0 to true. Be sure to clear your kernel cache afterwards if editing the Info.plist in place. It was cáusing problems with résetting the connection státus ánd DHCP stuff when thé cable was disconnécted etc. The kext in the Debug folder is mostly the same as the regular kext, but prints much more information to the system logs. I cant provide serious help or even guarantee a reply if things dont work for anyone. Enjoy. Torturing the driver by pulling the plug and soforth seems okay, but sometimes stuff like the AFP server can mess up.
