Problem with wlan sticks module, not able to write to disk any more (Page 1) / Kernel & Hardware / Arch Linux Forums

Hello everybody,

when I booted my PC today, a strange and some sort of severe problem occurred concerning my wlan stick(s) that I think, I'm not able to solve without your help. I searched for a solution but it didn't seem that somebody else has had a similar problem before.
Here is the description:
I have two wlan sticks (but I do not use both of them nor are they both plugged in at the same time), and both happen to malfunction since today. My "main" stick (used most of the time) is a BigTec Wireless 11N Adapter with a Realtek chipset. My second one (only used to solve problems with the other stick) is a Fritz! WLAN USB Stick (to be used with ndiswrapper).
After bootup, which makes no problems at all, my "main" wlan stick is not able to connect to the network. When I run wicd-curses (I use wicd as network manager), the virtual terminal freezes (when I use urxvt under openbox to run wicd-curses, only the window freezes). After one minute, a message appears that says something about a dbus problem but I am not able to read it because of the screen clears. Then I'm able to use the terminal again, but (and this is the very, very strange about this) when I run any program that tries to write on my disk it stucks, so I can't cancel it with ctrl-c nor can I kill the process. Wicd-curses, ifconfig or iwconfig also crash after entering the command and show the same behavior. At this point, my wlan stick does not show any sign of being plugged in (normally it blinks...).
My second stick makes the computer crash: After a few moments a stacktrace is shown (like when a kernel panic occurs), saying something about "stack being overrun". But I can't find the message in the log files so it is difficult to post it.
When I tried to figure out a solution, I saw in pacman.log, that yesterday udev and hwdetect were updated... But also downgrading all the packages that were updated yesterday did not solve the problem!
I'll post now the last lines of a few logs here (but nothing concerning the ndiswrapper stick, else it would be too disturbing), I hope they help you at helping me!
