           Summary: X goes to 100% cpu on start with GeForce 9400 (0x086a,

        OS/Version: Linux (All)
            Status: NEW

         Component: Driver/nouveau

GF9400: dmesg

When starting X.org server on GeForce 9400 (0x086a, C79, x86_64, DVI monitor
with 1360x768 resolution), the screen is completely white (except for mouse
cursor) and X starts running on 100% cpu (this is SMP system, so it doesn't
render the machine unusable). X seems to be locked up (e.g. numlock doesn't
work), but mouse cursor continues moving.

This happens both with and without KMS. DRM from 20090816 and DDX from
20090815. KMS console works correctly (though I do see "GPU lockup -
switching
to software fbcon").

Attached dmesg and X.org log, with KMS enabled.

Could I get you to grab a mmio-trace of the NVIDIA binary driver initialising
your card please?  There's detailed instructions at
http://nouveau.freedesktop.org/wiki/MmioTrace

Thanks!

It took a bit longer than I had hoped, but I finally got the mmiotrace (yes, I
didn't forget how to make those in just one week ;).
I sent it to the mmio dumps address, and also put it here:
http://stuff.onse.fi/nouveau/10de-086a/

It seems there was a kernel WARNING "kmmio_page_table not empty at cleanup,
any
further tracing will leak memory", but as that happened after stopping
trace, I
guess it didn't affect the trace itself.

Oh shoot. Maybe someone broke it. I haven't checked if it works for a long
time.

Yeah, that one does not affect the trace, but I wonder if something else is
broken, too. Gah. At least the size of your trace is decent, and people will
probably tell me, if there's something really wrong in the tool.

Seems to be working with current git.
