Details
I use NetworkManager to connect to a WPA enterprise wireless
network. After a few repetitions of the following
# systemctl stop NetworkManager # rmmod b43 # rmmod ssb # modprobe ssb # modprobe b43 # systemctl start NetworkManager my entire system freezes -- not even the magic SysRq key does anything. * This happens both with b43 (as above) and with broadcom-wl. * This happens both with dhcpcd and dhclient. * This happens with 3.14.x kernels but not 3.13.x kernels. It seems that this has something to do with releasing the dhcp lease: the last thing I see watching journalctl -f before the freeze is something of the form May 22 20:44:21 <hostname> dhclient[1624]: DHCPRELEASE on wlan0 to <IP> port 67 There are no logs or coredumps from the event that I can see after rebooting (so the line I copied above is from an iteration that did not actually trigger the bug). Other information: # lspci -vvv | grep -i wireless 02:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01) # uname -a Linux hostname 3.14.0-4-ARCH #1 SMP PREEMPT Wed Apr 9 21:11:25 CEST 2014 x86_64 GNU/Linux I'm not really sure how to provide better information about this, seeing as it leaves no trace in the logs. |
