Red Hat Bugzilla – Bug 470327
ifup eth0 causes link renegotiation and doesn't wait long enough
Last modified: 2014-03-16 23:16:23 EDT
Description of problem:
On my Intel Cantiga laptop using e1000e driver, the link negotiation seems to take a long time on certain LANs. The ifup process fails because it resets the link and does not wait long enough for the link to become ready.
Version-Release number of selected component (if applicable):
initscripts-8.85-1 from 10-Preview release
Steps to Reproduce:
1. boot computer with LAN cable attached and ONBOOT=yes config
2. LAN isn't ready soon enough
3. eth0 is not configured
No net is configured.
Process should wait longer for LAN link and then do DHCP config.
I think this may be an environment where the hardware is having trouble deciding whether to use 1000baseT or 100baseT speeds, so it takes longer.
You can set LINKDELAY in your ifcfg file to choose a more appropriate delay for your system.
