Here is a similar problem, maybe.
Unfortunately, I could not repeat the problem, and I was fooling around with
NetworkManager at the time - disabling and enabling wireless and changing
between various APs.
The good news is that iwl3945 and NetworkManager managed to work in other
conditions, and didn't fail at all when I rebooted to the current version of
F9beta.
Peter, I believe the issue you are seeing is actually the same as in bug 438584 -- please use that to track the issue. Created attachment 299218 [details]

Actual results: excerpt Mar 25 17:57:51 f9 console-kit-daemon[2135]: WARNING: Couldn't read /proc/2875/environ: Error reading file '/proc/2875/environ': No such process Mar 26 04:15:30 f9 kernel: warning: process `system-config-f' used the deprecated sysctl system call with 1.23.

"a" becomes "aaaaaaaaaaaaaaaaaaaaaaaaa....." same seen on F8 kernel since 2.6.24.3-34.fc8 [1] I got two of this prism54 cards. up to F9 beta on this box, where this bz is about, always isl3886 firmware was loaded eg. p54pci module was active. on the other box was always isl3890 firmware loaded eg. prism54. both cards were operating.
