Public bug reported:
WL module fails to compile, apparently new kernel (2.6.37) no longer has
init_MUTEX -function. Network stops working once one puts computer into
hibernation, suspend or reboots.
Workaround is to replace "init_MUTEX(&wl->sem);" with "sema_init(&wl->sem,
1);", then "depmod" and "modprobe wl".
