It seems Debian kernels are built with PCIEASPM=y so I added
pcie_aspm=off as a boot parameter, but still I got the crash :-(.

Then I tried your patch (against compat-wireless) and that still crashed
too :-(.

I couldn't use the setpci hack from the ASPM web page either because
lspci didn't produce usable results:
