EeePc 900HD - Kernel panic when bringing down wlan0 with Function Key

Hi everybody!
I'm experiencing this hitchy problem with this newly "purified" netbook (purified means i got rid of windrlors ). I'm a bit stuck, because i don't see anything on the logs ecc... since... well it panics out...
Basically, when i boot up, the wlan interface is always down. I can easily bring it up with the function key and  of course i can disable it with NM or iwconfig, BUT if i press again the FK to shut it down, the kernel panics out and X freezes badly. I can tell it's a kernel panic because the battery led starts blinking...

I'm runnig the stock kernel with acpid running.
lsmod out:

Also the other FKs work fine... Dunno, any ideas?

Re: EeePc 900HD - Kernel panic when bringing down wlan0 with Function Key

I assume you run X while trying this, which is probably why you don't see the actual kernel-panic. That message would be quite useful though, so I would boot into single-user mode, maybe tail some logfiles, and then perform the operation that causes the panic. When you have the actual message, it should be easier to fix!

Re: EeePc 900HD - Kernel panic when bringing down wlan0 with Function Key

Nope... seems it's a long time known/unresolved bug in the kernel. Somebody made a kernel patch, but it wasn't accepted upstream, and now is too old.

Too bad.

Well for the moment, do somebody know of a  way to disable this acpi event?
