Red Hat Bugzilla – Bug 215765
DHCP failure with tg3 (BCM5752M)
Last modified: 2014-06-29 18:58:06 EDT
Description of problem:
I just got a shiny new laptop, a Lenovo z61t. After a couple of failures in
unrelated components, I have narrowed my current problem:
1. Boot the kernel in single user mode (2.6.18-1.2747.el5)
2. Start the network (service network start); at this point, the machine will
bring up the tg3 as eth0, DHCP, and get an address. All is well.
3. Restart the network (service network restart); at this point, the machine
will try to DHCP again, but will fail to get an address.
The tg3 card in question is:
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5752M Gigabit
Ethernet PCI Express (rev 02)
I've tried rmmod'ing and modprobe'ing the driver to reset it, to no avail. I
also tried manually setting an IP address to the interface (ifconfig eth0 <ip>
netmask <netmask>), which also fails. It seems that once it DHCP's a first
time, it can never be brought down, or it will fail. This wouldn't seem that
important, except that the ability to re-DHCP is required for Xen to function
