Description Fabrizio 2010-01-29 13:15:51 UTC

I have a wireless card AR928X Wireless Network Adapter, and use openSuse 11.2.
When I use the wireless card too much (downloading a lot of things), I hear a system beep and suddenly connection breaks up and it doesn't connect until reboot.



This is what I get (localmessages):

Jan 29 11:29:21 linux-g3rs checkproc: checkproc: can not get session id for process 2361!
Jan 29 12:08:00 linux-g3rs checkproc: checkproc: can not get session id for process 2366!
Jan 29 12:10:36 linux-g3rs checkproc: checkproc: can not get session id for process 2135!



This is what I get on the screen:

Comment 1 John W. Linville 2010-05-12 18:16:46 UTC

What kernel version are you using?  Does the problem exist on current linux-2.6 kernels?

Comment 2 Fabrizio 2010-05-14 08:46:16 UTC

Yes, it exists; I'm using the last updated versions of openSUSE and Debian, and I'm getting the same error. It is an error related to kNetworkManager, now I'm using iwconfig and dhclient (Debian) and I'm not getting errors anymore.

Comment 3 John W. Linville 2010-08-13 16:14:44 UTC

I'm sorry to seem dense, but did you actually try an upstream kernel?  Or only "last updated versions of openSUSE and Debian"?  Those are not at all the same things.

Please replicate the problem with a 2.6.35 (or later) kernel and post the current backtrace here...thanks!

To: linville@tuxdriver.com

I can't reply online, because i don't have access anymore to
bugzilla.kernel.org.
The problem doesn't affect today kernels in Debian, OpenSUSE and Fedora. Now my
card is working

very very good.

See ya
