Dell XPS M1530 wireless configuration

Hello,

I've just installed FreeBSD for my first time on my laptop, and I have encountered a problem with the wireless card configuration (BROADCOM BCM4310). Specifically, when I try to change the wireless interface's state to "up", the system freezes. Here is the output:

Code: 
[root@vasilis-freebsd vasilis]\$ ifconfig wlan0 up
Sleeping thread (tid 100211, pid 1854) owns a non-sleepable lock
panic: sleeping thread
cpuid = 1

Here are my configuration file entries

/boot/loader.conf
Code: 
if_bwi_load="YES"
bwi_v3_ucode_load="YES"
wlan_wep_load="YES"
wlan_ccmp_load="YES"
wlan_tkip_load="YES"

/etc/rc.conf
Code: 
wlans_bwi0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"


/etc/wpa_supplicant.conf
Code: 
eapol_version=1
ap_scan=1
fast_reauth=1

network={
}

network entry in wpa_supplicant.conf is empty because when network info is provided, the system freezes during boot-up.



Here is ifconfig output:

Any ideas on what's happening folks?
 
I found it quicker to install an edimax usb dongle (one with a large antenna for better reception) (a/b/g) than use the broadcom & ndis... but have you tried booting with acpi disabled? Or maybe an irq conflict in the bios on that machine? I never really figured out the ndis steps and proper files to use...
 
Issues with connecting to WiFi

[ Merged in - removed [Solved] tag -- Mod. ]

Hello! I'm having the same issue as the OP in this thread.

I've applied the patch but this doesn't change anything for me and the issue remains.

Unlike the OP in the mentioned thread, I haven't updated any .conf files yet but I would think that this wouldn't make a difference with this issue.

If there's anything else someone needs to know that's not in this thread let me know.
