Description John W. Linville 2005-07-01 20:33:38 UTC
+++ This bug was initially created as a clone of Bug #161846 +++

Description of problem:
Sometimes the following message appears when trying to set up the eth0 device:

[root@bofh /tmp]# ifconfig eth0 up
SIOCSIFFLAGS: Cannot allocate memory

[root@bofh /tmp]# ifconfig eth0
SIOCSIFFLAGS: Cannot allocate memory

This only happens with the primary interface, a b44 ethernet controller.
Wireless and a second usb nic do not show these problems.

The nic in question:
01:0e.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
        Subsystem: Hewlett-Packard Company: Unknown device 08bc
        Flags: bus master, fast devsel, latency 64, IRQ 11
        Memory at 90080000 (32-bit, non-prefetchable) [size=8K]
        Capabilities: [40] Power Management version 2

The installed kernel is 2.6.9-11EL, but this problem happened with earlier
kernels as well.

Better implementation...

Comment 7 John W. Linville 2005-08-26 19:31:54 UTC
Test kernels w/ above patch available here: 
I'd love to hear from anyone that has experienced this problem on RHEL3... :-) 

Comment 14 Ernie Petrides 2005-10-27 02:23:39 UTC
A fix for this problem has just been committed to the RHEL3 U7
patch pool this evening (in kernel version 2.4.21-37.7.EL).
