kernel stack clearing isn't hard to do, just do it on every syscall exit

Actually that is probably not as important. In most

Even when this works around it, the problem that the kernel triggers
module loading on /dev/console access stays and needs to be fixed
instead.
It isn't a problem. It is trying to have hotplug load a suitable driver.
This is what is supposed to happen.

No, it's not. 5:1 is _in_ the kernel, and must not be tried to be
loaded by the kernel. We need to make /dev/console access return

/dev/console is a logical mapping to a device which may well be
different, loaded after PCI is initialised and dependant on PCI.

Heh, init is not allowed to write something to the console or any other

So wrong. If no driver is associated, like early, in that case, we
must return -ENODEV, instead of calling modprobe in a loop. It's a

No. Please back up what you are trying to talk about.
