Strange freeze and kernel Oops

For some time already my system often (50/50 chance...) freezes within about 1-2 minutes after booting... At first I thought that these are Xorg freezes, but then, after not starting Xorg once, I noticed, that I got this message after a short time:

After that the system is very unstable, freezes on Xorg startup for sure and sometimes just on the tty or even during shutdown...

This happens only within the first few minutes and if it doesn't, the system works just fine... Can somebody explain what is going on and how to fix it?

Thanks in advance...

Re: Strange freeze and kernel Oops

Some old module which hasn't been recompiled for the recent kernel, while meanwhile the api has changed enough to make trouble?
Or the system is getting unstable because of failing fans, powersupply, ram, overclocking, whatnot? (hehe, keine panik)
Personally i have seen similar things with OSS (a few weeks ago?) but not in the aes-module. i just deinstalled OSS, and then reinstalled it.

Re: Strange freeze and kernel Oops

The reason could be a panic while attempting to connect to wireless network. If u can disable your wireless card and see if the problem occurs it can narrow the search...

Re: Strange freeze and kernel Oops

Thank you for the suggestions... I disabled the sensors_lm and wicd daemons and will look for a while whether this makes a change or not...

Re: Strange freeze and kernel Oops

Then it looks like that the problem is not with network managers, could be a bug in rt73usb module...

Re: Strange freeze and kernel Oops

Ok.. if its a bug in rt73usb, then why there is written:

Oops: 0000 [#1] PREEMPT SMP

and I have no problems for the last 2 days, after having removed the wicd-daemon from the rc.conf and starting it after the desktop manually, although the module is still in my rc.conf?

If it really is a rt73usb bug, then one with really strange cross-reactions...
