FOUND A WAY TO REPRODUCE BUG, WIRELESS ADAPTER IS THE PROBLEM

I made an earlier post saying that I will take out my wireless adapter before I start my computer up and see if I still get the hard lockups. I tried it out last night, and sure enough, when Hardy started up without my wireless adapter plugged in, it ran beautifully. For 35 minutes, I ran all sort of different programs, too many to list. I then plugged in my wireless adapter. For a few seconds, nothing happened. Then the network applet in the top right showed that it was identifying and connecting to my wireless internet, and as soon as it showed 4/4 bars for the established connection, Hardy froze completely.

Now I can reproduce the lockups easily, and that explains why Hardy locks up only seconds after I log in when I have my wireless adapter plugged in on startup.

By the way, I used this wireless usb adapter without problems with a different computer, on which I had installed Ubuntu 6.06 and 7.04. So I'm not sure how to proceed from here. Is it a driver issue? Is there a conflict between the wireless adapter and the kernel? Ubuntu is useless to me without an internet connection.

Also, when I got my first lockup, I had just installed Hardy, and I was using it for hours, with internet and all, until I got a (soft?) lockup in which I could move the mouse, but nothing else. The only other thing I could do was Alt-SysRq-R-E-I-S-U-B, and for all (two) of my subsequent boots in Ubuntu, Hardy froze within seconds of my logging in. So for those two times I logged in, and Hardy froze seconds afterwards, it must have to do with my wireless adapter. However, the first time I got the soft lockup, I was using my wireless adapter. What was causing that lockup? I have not used Hardy much since...could that lockup have been caused by a disk I/O issue? Even if I took out my wireless adapter, could a similar soft lockup occur again at seemingly random times, like the lockups all of you are experiencing? Hopefully that lockup had to do with my wireless adapter too. I will look at the syslog for that day I got the soft lockup and see if anything was reported.
