Hi all,

I'm having a problem with my net6501 when trying to install CentOS (RHEL) 
Linux, both with the latest version (6.2) and the latest previous release (5.7) 
using PXE booting to bootstrap the install.

In essence, at some point during the install (the exact time varies and is 
unrelated to initial interface activation by the installer) the network 
interface will just hang. The LED is still lit, but the light doesn't modulate 
with traffic on the line. Pinging from the net6501 as well as the LAN it is 
connected to results in an error as if the network cable has been pulled. The 
network settings on the net6501 look fine, but the interface shows errors 
registered when running ifconfig.

- to isolate issues with specific interfaces I have tried running the install 
from all ethernet ports on the net6501 without a change in behavior

- to make sure this is not a problem with broken interface speed negotiation I 
have set the switch port it is connecting to to a fixed 100M/full duplex value 
and disabled auto-negotiation. The switch is a HP ProCurve 2810-24G. 

- to exclude specific switch interoperability issues I even tried with an 
intermediary switch, an old Cisco 2850.

- as mentioned above, I tried two different CentOS versions

- with a bit of fiddling I managed to upgrade to the lastest BIOS release, 
1.41a, which fixed a serial port output display issue for me but my network 
interface problem remained

Can anyone suggest a solution or other things to try?

Thanks!
