Yes it does. Sorry for not mentioning this. I used pci=noacpi the last few
weeks. This makes the wireless card use IRQ 10
It doesn't work very well thought, the IRQ10 and IRQ5 are unstable and the
wireless and the sound block each other(Both IRQ 10), as well as USB and
ethernet(IRQ 5). Additionally, DRI is unstable after resume.

I modified my DSDT to use IRQ 10 for LNKE, and that makes my system work
perfectly. Is this a workaround or can I consider this a solution. The
problem is, that half my hardware uses irq10 while the irqs 4,6,7,11,14 and
15 are unused.
Shall I upload my modified dsdt? I think so.
