Classification: openSUSE Product: openSUSE 12.2 Version: Factory Platform: i686 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: fzambrini@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=467979) --> (http://bugzilla.novell.com/attachment.cgi?id=467979) Info for Acer Aspire 3680 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:8.0) Gecko/20100101 Firefox/8.0 Iceweasel/8.0 Operating System: Debian 6.0 Squeeze Kernel Version: 2.6.32-5-686 and 2.6.38 (backport kernel) Hardware: Acer Aspire 3680 Problem: If the acer-wmi module is loaded, gnome network manager will repeatedly (and randomly) disconnect and reconnect to the wireless network. If the acer_wmi module is blacklisted, gnome network manager will behave normally. However after 2-3 cold boots, the wireless interface (wlan0) will be permanently disabled. The only way to fix is to reload acer_wmi and reboot. Reproducible: Always Steps to Reproduce: 1. Load acer_wmi at boot up Actual Results: Gnome network manager randomly disconnects and reconnects. Expected Results: The network connection should be maintained constantly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I didn't see useful information from dmesg. (In reply to comment #5)
Attached are the dmesg and messages logs. The network connection was lost twice in this time.
'watch -n 1 rfkill' did not work so I used 'rfkill event' instead.
I also discovered that this bug affects 2.6.39 from Debian backports. (http://packages.debian.org/squeeze-backports/linux-image-2.6-686)
Let me know if you need any more information/testing.
Sorry for my command is wrong, please use: 'watch -n 1 rfkill list' Then, please monitor does there have any state of rfkill changed (soft/hard block) when issue happen? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It doesn't happen every time I unplug the psu but it seems like the problem is more frequent when on battery power. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I believe acer-wmi still running the polling thread to read the hardware status on your machine, and the wmi or EC register might response wrong status.

I was unable to apply your patch to the current version 3.2.0, so I ended up patching the standard 2.6.32 kernel. After reloading the acer_wmi module, I tried to reproduce the bug but was unable to (i.e. I never lost the connection). The attached log from dmesg shows when I loaded the new acer_wmi module at 919. Note: The bug is reproducible in the 3.2.0 kernel from debian backports. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Yes, you can not reproduce issue because I removed the statement for setup rfkill state in acer-wmi. And, I put a log to acer-wmi by my patch.

When I tested your patch, I did not change the wifi state. The only thing I did was unplug the AC power adapter as this would sometimes trigger the bug.
