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.

For some other reason I cannot achieve a proper install right now so I can confirm only with the live CD, but symptoms are exactly the same as above : boot ok, user session ok, if I click on the NetworkManager icon I can select the network, then connect to it, enter my WEP key, and then the system will freeze (while asking for the keyring password, secondarily). If I don't try to connect, everything works fine but the system won't shutdown (didn't try to logout).

Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

It gets past setting up the wlan0 every other boot or so. Once it is up and running, everything is fine. I tried suspend and resume once, and that locked up on resume too (even though this is a desktop, it should still support s2r). I'm currently doing a "yum update", I'll report again with the results of the latest kernel.

It looks like a drm/i915 bug. But it takes out the network too, although I don't know why. It looks like I'm hitting this bug: https://bugzilla.redhat.com/show_bug.cgi?id=573177 As far as I can tell from the logs when it locks up now. It does not seem to be related to the wifi nic, but to the video. I don't understand why I lose my wireless on the X lockup. I'm fine on serial. I'll try again with a wired connection, but as far as I'm concerned, it looks like this BZ is done. I would like a working system before I conclude that though ;-) Reply at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/839019/comments/11 ------------------------------------------------------------------------ On 2010-05-27T19:05:20+00:00 Steven wrote: Interesting, after pulling the pci wireless card, I can not make X lockup.

It just means the card you own works fine with it.... Btw do you own a realtek branded one ?
