Upon reboot, computer freezes when trying to activate wlan Linksys wireless 54gV4 PCI wlan card (RT2500 driver). Works fine under prior kernel. No messages in log, no kernel panic,just hard freeze when trying to activate card. Version-Release number of selected component (if applicable): kernel-2.6.25.4-10.fc8 How reproducible: Always Steps to Reproduce: 1.boot kernel 2.6.25.4-10.fc8 2.try to activate wlan card eithe automatically in Network Manager, or manually 3.computer hard freezes Actual Results: computer hard freezes, can only power down and reboot. works fine under prior kernel. Expected Results: wlan card should have activated. Additional info: None. Nothing is written to log
This has been happening to me on older fc8 kernels too. And it also happens on fc9 (2.6.25.4-30.fc9.i586). My hardware is a PCMCIA rt2500 card (Edimax), which was usable with the old ralink driver. When I plug in the board, the driver is loaded and the system locks up immediately or after a few seconds (memory corruption). A stack trace of mine is available here: http://www.kerneloops.org/raw.php?rawid=22175 Finger pointed to locking, interrupts, sleeping in the rt2500 driver.
I too get this with a Ralink RT2500 PCMCIA card with the latest Fedora 9 kernel (to date). Can look up more info later if you wish. The previous Fedora 9 kernel works fine, but the latest one crashed a second after you plug the card in. The kerneloops service has reported the incident. As I say, ask if you want more info.
I have the same problem. In fact at boot up with the wlan card acitivated at boot the system try to enable wlan0 for an infinte time. If i disable wlan0 at boot and i try to activate wlan0 from grome i obtain a hard freeze.
Please try -39.fc9 or later: http://koji.fedoraproject.org/koji/buildinfo?buildID=50951 Those contain this fix: "rt2x00: Use atomic interface iteration in irq context". Do the later kernels resolve the issue for you?
I tried kernel-2.6.25.6-24.fc8 which is an updates-testing and contain this fix. No more hard freeze but impossible to associate to the access point.
Yes, I can also verify that rt2500pci from kernel-2.6.25.6-24.fc8 does not associate with the AP.
Created attachment 309399 [details] excerpt of var/log/messages containing wlan activation attempts
Addendum to comment #7 (sorry for multiple posts). Tried kernel 2.6.25.6-55.fc9. Hard freeze now gone, but cannot associate with AP either. Messages in above attachment. AP is WPA2-PSK. Original passphrase stored in keychain, but after first attempt, NetworkManager prompts me to input, but activation fails anyway, and I get prompted again (until I cancel).
Created attachment 309979 [details] dmesg with kernel errors after inserting rt2500 card I get kernel error messages but no hard freeze with the rt2500. With testing kernel no errors but can't associate with AP. Another card with a differnt chipset works fine.

Association still times out with kernel-2.6.25.9-40.fc8
Kernel 2.6.25.6-27.fc8 fixed the hard freeze for me and works like expected, but with kernel 2.6.25.9-40.fc8 I cannot associate using wpa_supplicant.
You might wisht to try -46.fc8: http://koji.fedoraproject.org/koji/buildinfo?buildID=54856 Does that help with wpa_supplicant?
Created attachment 311195 [details] log of failed association still unable to associate with -46 kernel
For me too, still unable to associate with -46.fc8 kernel
Same story with both -47.fc8 and -48.fc8.
Same with kernel-2.6.25.11-54.fc8 This bug is opened since 5 weeks. It's quite a long time ...
Just tried 2.6.26.3-5.fc8 from Koji. Still doesn't work .. (i.e. authentication with AP times out).
Hmmm...well "AP times out" sounds different than "hard freeze". Perhaps the problem you are seeing now is the same as bug 451422?
John, problems of association and times out are part of this bug since a long time see for example comment 5.
Hi John, I suppose it might be same as bug 451422 but the end result is still the same. I've had to stick with a 2.6.24 series kernel for at least two months now ..
Please use bug 451422 for the association problems. I'm sorry I didn't notice the change back in June. *** This bug has been marked as a duplicate of bug 451422 ***
