Let me just say, this hasn't been happening ever since I installed it. It only started a couple of weeks ago and since then, I'm pretty much rolling the dice when I open something like Konqueror. It might work... or the first website I go to the system will page fault, lock up for 15 seconds, and reboot.

Text based browsers like lynx work OK.

I've been saving the results of each vmcore backtrace and they all say the same thing. There's a problem with my wireless, starting somewhere between ural_txeof() and ieee80211_free_node().

I use a Linksys Wireless-G USB adapter - does anyone else here use this without problems? - and have wpa_supplicant enabled.

And if anyone is thinking of asking the obvious, no, I haven't customized my kernel.

If someone could help me find out what's going on, I'd appreciate it.
