output of dmesg

After booting a system with Fedora 21 the screen does not switch to graphics
mode on start of kde and keeps displaying the last lines of the text mode boot
log.
Switching to a text console using alt-Fn key combinations does not work.
System is otherwise working, using ssh to log in remotely works.

Last line from noueveau in dmesg shows it failed in nouveau_channel_idle:

Hmmm... so it hangs right on start.

Did this particular GPU work with older kernels?

Perhaps MSI is messed up for some reason? Can you try booting with
nouveau.config=NvMSI=0 (or pci=nomsi)?

Thanks for the fast reply.

Haven't tried this particular machine with older kernels yet as i was
attempting to upgrade from Windows Vista to Fedora 21 and am now trying to get
something else but Vesa drivers with 1024x768 to work.
The system did work fine with that other OS.

Booting with nouveau.config=NvMSI=0 is a working.
Thanks for the hint, now to find some info what that actually does :-)

As i have a solution for my issue i wonder whether i should change the status
to resolved already.
I'd still prefer to find out why the parameter is necessary.
If the logic when it is necessary is known there might be a way to get the
Fedora installer to automatically set it.

Suggestions whether to leave this open and provide more information or to close
it are welcome :)

Let's leave this open -- disabling msi should just be done as a temporary
workaround. Ideally we'd detect that MSI doesn't work (or perhaps it's not
being enabled properly).

Is this a PCIe card, or a PCI card? Could I trouble you for the output of
'lspci -vnn -t' ? (Perhaps this information is available in your lspci -vv
output, but I don't know how to read it.)

Can you provide 'cat /proc/interrupts' when you don't boot with the MSI disable
and ssh in to obtain it? If any of the other devices are marked as PCI-MSI-*,
are you having trouble with them?
