I don't see a panic here. Also, your kernel is tainted "C" (crap, staging module or vbox), and what we see here isn't the first problem. As the kernel doesn't actually panic as far as I can see here, can you please try to save dmesg?

dmesg & netconsole-logged panic/warning/whatever with untainted kernel

Hardware: Acer Aspire 4740 (Broadcom chip with ath9k chip)
Software: Linux-3.1-4 & wpa_supplicant v0.7.3
Closely related but not the same problem (my system doesn't have have the bcma as mentioned in the url): https://bbs.archlinux.org/viewtopic.php?pid=1014217
Observation: No such network stall with linux-3.0.7-1.

I didn't encounter core dump problem with kernel 3.1. However, after connecting for a few seconds or minutes, the connection with stall and I can't assess Internet. I check my dmesg, it gave the following info:

[ 45.966602] wlan0: direct probe to f4:3f:61:06:22:21 (try 1/3)
[ 45.969213] wlan0: direct probe responded
[ 45.998789] wlan0: authenticate with f4:3f:61:06:22:21 (try 1)
[ 46.001234] wlan0: authenticated
[ 46.001270] wlan0: associate with f4:3f:61:06:22:21 (try 1)
[ 46.004102] wlan0: RX AssocResp from f4:3f:61:06:22:21 (capab=0x411 status=0 aid=1)
[ 46.004107] wlan0: associated
[ 93.007527] usb 1-1.3: USB disconnect, device number 3
[ 95.654157] NET: Registered protocol family 10
[ 106.263062] wlan0: no IPv6 routers present

Does this mean that the IPv6 in kernel 3.1 is affecting the wifi connection?

I am not sure if my problem is the same as this category. I feel that it is some how related. Let me know if it's a different problem so that I create a new task for my problem.
