In case you didn’t know, MacPro’s with 10.4.10 are connecting at 10Mb speeds to 1000Mb switches and hubs… bummer :(<\/p>\n
So a kext is the culprit:
\n\/System\/Library\/Extensions\/IONetworkingFamily.kext\/
\nContents\/PlugIns\/AppleIntel8254XEthernet.kext<\/p>\n
In 10.4.9 it’s version is 1.1.7a3, in 10.4.10 it is 1.1.8a2, in 10.4.11 it is 1.1.8a6
\nThat doesn’t matter much really, but that’s the details.<\/p>\n
So you gotta roll back the kext:
\n1. Get the 10.4.9 Intel Combo Updater
\n2. Get OpenUp or Pacifist
\n3. Open the DMG
\n4. Show contents on the PKG
\n5. Copy out the pax.gz file to the desktop
\n6. un-Gzip the pax, and open that up (with Pacifist or OpenUp)
\n7. Get the old IONetworkingFamily.kext
\n8. Copy it into your \/System\/Library\/Extentions<\/p>\n
Now, the ownership on the kext need to be changed to root:wheel or if you’re in Finder system:wheel And yes, the 10.4.11 seed update corrects this.<\/p>\n Bonus Log files: These have been “prettied up” for readability, but you’ll see, 10.4.10’s driver is just spitting out Zer0s so the network switch\/hub has no choice but to say “O K… I ‘ l l s p e a k s l o w e r t h e n…” <\/p>\n 10.4.10: 10.4.11(seed, much prettier logging in this kext): If this info from 10.4.11 is NDA well bite me, I think people should know it’ll be fixed in the future, right? :)<\/p>\n","protected":false},"excerpt":{"rendered":" In case you didn’t know, MacPro’s with 10.4.10 are connecting at 10Mb speeds to 1000Mb switches and hubs… bummer :( So a kext is the culprit: \/System\/Library\/Extensions\/IONetworkingFamily.kext\/ Contents\/PlugIns\/AppleIntel8254XEthernet.kext In 10.4.9 it’s version is 1.1.7a3, in 10.4.10 it is 1.1.8a2, in 10.4.11 it is 1.1.8a6 That doesn’t matter much really, but that’s the details.

\nsudo touch \/System\/Library\/Extensions<\/code>
\nthis changes the date stamp on the directory and OS X will recreate the kernel caches…<\/p>\n10.4.9:
