Kernel OOPS - unable to handle kernel paging request

[Lorenco Trichardt]

I have seen a couple of bug reports on the Intrepid kernel:
I have an idea that mine is a dup of Bug #275359 but I have been unable to get a look at the oops....
I am running wireless lan and have seen people reporting from Thinkpads....

I will be trying to get a look at the oops and will attach more details then.

Thanks Lorenco,

Yes, please attach more info regarding the oops when you're able to get it. Thanks.

I see some funny errors in the dmesg >
Could this be related?

I mannaged to get the following during the night:
The machine did not freeze like last time but I did lose my wireless link and then it froze on the reboot ...

This appears to be a bug in the atheros/madwifi hal. Something we can't fix, because it is a closed binary blob. I would take concern with the nmi error shown. It clearly says you have a hardware problem. It may be that the hardware problem (likely on the PCI bus) is somehow triggering the crash in ath_hal.

Closing as wont-fix
