Created attachment 108471 [details] config file used in 3.10.12 kernel system: CentOS 6.4 i686 SELinux enabled: yes bug kernel tested: 3.10.12 non-bug kernel tested: 3.4.61 3.4.62 3.2.50 3.2.51 When?: Always custom cmdline: security=selinux selinux=1 nordrand crashkernel=0@0 hardware: Lenovo t400 wifi card: 03:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection External tracker: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165433 When a DUN connection is enabled using network manager from gnome 2.28 on CentOS 6.4 i686, and is disconnected and later reconnect to a wireless WiFi connection the system freezes totally or kernel panic. 3.4.x branch is not affected. The bug is reported in launchpad, and still since 3.8 branch, so the regression is introduced in 3.8 and still in 3.10.12 stable long term. Steps to reproduce it: 1.- Use a vanilla kernel 3.10.12 2.- Connect a DUN connection to a cellphone using network manager 3.- Disconnect the DUN connection from network manager 4.- Connect to a WiFi connection 5.- Crash Attach .config of 3.10.12.
Hmmm...not sure if this is Bluetooth or 802.11 driver...
(In reply to John W. Linville from comment #1) > Hmmm...not sure if this is Bluetooth or 802.11 driver... No idea, but using 3.4.x and 3.2.x no problems. The bug was introduced in 3.8 branch.
does the bug still occur on recent kernel?
