Hi,
For some reason my network card started going 10Mb/s half duplex instead of 1000Mb/s full duplex. System is connected to 8x1Gb HP switch.
Other devices connect fine through the switch and get full 1Gb network.
I have Centos 5 with all updates. Driver comes from elrepo and as well is updated.
Any input much appreciated.
Thank you in advance
Chris
