firefox does not start with 6.8-rc

[Philipp Hortmann]

Hi,

compiled the latest staging kernel on my xubuntu laptop. It starts fine 
but I cannot start my firefox anymore. This happens only with kernel 
6.8-rcx. With kernel 6.7 no issue at all. Find logs below. Found in some 
forum that it is fixed in some later rc on an other tree. Tried to find 
this patch series that fixes this. But was not able to.

But anyway is this a kernel issue? Do the kernel developers care?

Thanks for your support.

Bye Philipp
