Bug Description
On computers with some rtl818x chip based wifi cards, when module rtl8180 is modprobed this causes a complete freeze of the system.
This issue is severe for two reasons:
* computers with such wifi cards aren't able to connect to their network via wifi through a native linux driver;
* because rtl8180 is modprobed at startup, when a new user tries Ubuntu on such computer, the liveCD will show a black screen without any error message, and then the user will blame Ubuntu.
Although there are already some similar bug reports, they are all too specific to another hardware so the aim of this report is to centralize any information about actual system freezes caused by rtl8180 modprobes. In addition, this bug has been initially described in previous bug #152527.
Affected Ubuntu releases: Intrepid, Jaunty, Karmic
Affected wifi cards :
* MSI PC54G3 III (chipset RTL8185L)
* Zyxel G-302 V3
Workarounds:
* ndiswrapper:
* works on Intrepid but not on Jaunty
* manual install of Realtek's supported driver:
* at least it seems it prevents the system from freezing
* still in testing: some can connect to the network, some not

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.
