NM NetworkManager locks up system w/Intel Pro 100
Last modified: 2007-11-30 17:12:18 EST
Description of problem:
On a PR400FX based system sporting an Intel Pro 100 NIC, NetworkManager
freezes the whole system when the latter is enabled at boot time.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Enable NetworkManager services.
2. Reboot system.
System freezes when NetworkManager services get started. Keyboard
LEDs blink. The system needs to be powered off hard.
System boot up normally.
This also happens all the time when a self-compiled kernel module
'acx.ko' was loaded in order to enable a DWL-G520+ WLAN adapter.
Moreover, this happens in 1 out of 2 times for an alternatively
installed DWL-G520 WLAN adapter driven by the proprietary 'madwifi'
driver. In this case, however, in 50% of the cases, the system
boots up normally, and NM can be used successfully to enable WLAN
