Uhhuh. NMI received for unknown reason a0 on CPU0 You have some hardware problem likely on the PCI bus Dazed and confused but trying to continue.

Could you post whole dmesg output when this happens? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I've been stressed by this wireless card since I got this T60 laptop about 2,5 years ago. (I had a Ralink card before which was even worse) Before 11.1 (I had 10.3 and 11.0 on this machine) I had to use self compiled drivers with the card. First madwifi and later the ath5k from compat-wireless. With madwifi there have been quite a lot of disconnects and NMIs with the card failing to reconnect after about an hour or so and denying to work again until rebooted or went through an suspend/resume cycle. The ath5k was very buggy at the beginning, too but has been getting better and better with the time. On openSUSE 11.1, with the integrated ath9k, I initially had more or less the same problems like now. Somewhen I decided to use the http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_11.1/ repository to check if a new kernel fixes it. I had varying experiences throughout different upgrades. But the 2.6.31 series has been quite stable with the card (at least after I disabled power management through 'iwconfig wlan0 power off'). But with openSUSE 11.2 (current official Kernel 2.6.31.5-0.1-desktop) I have more or less the same problems like on 11.1 again. May it be that there is some special patch on the stable 11.2 kernel that has not been in the HEAD repo for 11.1 and that could be causing this issue? By the way: Why isn't there a Kernel:/HEAD repo for 11.2 (yet) ?

You had to add yout pci id to the driver, right?

But the 2.6.31 series has been quite stable with the card

Could you specify exact version of a kernel which worked for you?

By the way: Why isn't there a Kernel:/HEAD repo for 11.2 (yet) ?

It appeared there already. Cpuld you attach output of lspci -nns 3: ? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'm very happy with this kernel. It's fast and stable. I didn't have any NMI or any other of the problems mentioned above. So there seems to be some problem with the 11.2 standard kernel or the ath9k driver which is delivered with it.

I thought there was a time when ath5k also supported the card (although not really well), before ath9k was introduced. But may be, that I'm wrong. Nevertheless, I'm very impressed with the new kernel from the HEAD repo. It gives me the best experience I ever had. Suspend/Resume works flawless, Wireless Connection is really stable and has a great signal strength. All NMIs have disappeared. And somehow I have the feeling, that the whole system feels quite more responsive. @Michael: I really recommend you to test it. I also had the problems directly after boot up. The wifi than reconnected and worked for some time before the connection break again. But after some reconnect cycles, it isn't able to re-initiate the connection. But there isn't such a problem with the new kernel. Which component does make trouble with standby? The WLAN only? Then just let the pm remove the module on suspend and reinsert it on resume. Works for me. And the T60 is a really good model for standby mode. The power consumption in standby is so low, that I can leave it in this mode for several days. So I only reboot the system after large updates (Kernel/KDE ...). -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In a few weeks I'll get a shiny new T410s, so I just try to keep the T60 working until then ... :) However, I don't remember getting any NMIs after the latest kernel update to 2.6.31.12-0.1.
