sosreport of the system

Description of problem:

Ther system experiences hard hang when using WIFI with the rtl8180 kernel module. The system ends in such a state that sysrq is inefficient (sysrq-t, sysrq-m, sysrq-c do nothing) and quite often require a complete electrical unplug for several seconds to be able to reboot.

Console logs or /var/log/message show no oops or kernel backtrace.

Blacklisting the module rtl8180 or removing the Belkin WIFI G PCI card cures the problem but does not help with WIFI connectivity ^_~

Version-Release number of selected component (if applicable):

kernel-PAE-2.6.29.3-140.fc11.i686 (But occurs on older kernel as well, including F10)

How reproducible:

100% reproducible

Steps to Reproduce:

1. Install the Belkin Wireless G dektop PCI card Based on the Realtek 818x
2. Boot the system

Actual results:

System will hang either at login or at logout

Expected results:

System remains stable and functional

Additional info:

The WIFI connection uses hidden ESSID and WPA/WPA2 security. The problem occurs either when NetworkManager connects to the network or when it terminates (logging out from the user session leads to a 100% hang).

Same happens if NetworkManager exits or needs to reconnect. The same hardware works perfectly under Windows with Belkin's provided driver though.

I am attaching the sosreport of the system, unfortunately I am unable to debug this issue much further and I could not come up with a usable workaround for the issue.
