Wifi gone after kernel 3.2.1 update

Hi, i have a realtek usb wifi adapter using with stock kernel. After the kernel update it stopped working. If i try to run netcfg, whole system went sluggish and konsole also stops working. This is not an issue with 3.1.9-2 kernel. I can only provide dmesg output; since somehow other log files last updated in October (i wonder why??)

dmesg output with linux-3.1.9-2: http://pastebin.com/3CSJ7psL
dmesg output with linux-3.2.1-1: http://pastebin.com/6WfKGDEJ

I have just opened a bug report (FS#27996) but i think there may be someone who knows a workaround . I already downgraded to 3.1.9-2 kernel and edited IgnorePkg line in pacman.conf

Does anyone have this problem with this wifi dongle?

Re: Wifi gone after kernel 3.2.1 update

I have the same problem as well, but with a similar chipset. Mine is Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter. My other dongle (Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 54Mbps Network Adapter) works fine though.
