Hi, On 3.12-rc1, modprobe brcmsmac causes a soft lockup (trace #1), effectively killing the box. This is a Lenovo S206 with BCM4313 (14e4:4727), which I believe is a bluetooth combo board. After a while, RCU scheduler code detects a lockup (trace #2). This did not happen in 3.11.1, although brcmsmac hasn't worked on this machine as far as I remember. In the previous kernels (~3.2.0+), it loads, but the reception is extremely weak - you must be within few meters to the AP, and the card would die after several minutes. The proprietary wl.ko driver works fine. I've attached the dmesg output, the kernel configuration and the output of lspci -vnn. I'm comfortable with experimenting; please let me know how I can help here.
A fix for this problem has been submitted to John. I think it is in transit to mainline so probably will be in 3.12-rc2.
