Xorg 1.9.0 Freezing Up

I have a Macbook Pro 4.1 and am running Xorg 1.9.0 with Fluxbox 1.1.1.  Every so often everything will freeze up for a couplt of seconds and then start up again, and when I do a dmesg I get:

usb 7-2: ctrl urb status -75 received

So it seems that for some reason my keyboard and touchpad are getting randomly disconnected and then reconnected, what could this be, and how can I go about fixing this?  Thanks.

Re: Xorg 1.9.0 Freezing Up

IIRC Xorg 1.9 and xf86- drivers have some issues. You can downgrade and see if your problems are gone.

Can you back this up with some more info?

Downgrading xorg-server should be relatively easy. If the issue is present with the previous version we need to try something else.
The other thing that comes to mind (actually, comes up in a search ;P) is https://bbs.archlinux.org/viewtopic.php?id=96516 but it's pretty heavy stuff.

Re: Xorg 1.9.0 Freezing Up

As far as I can see, kernel got a reconnect signal from usb hub stating that EMI (ElectroMagnetic Interference) could be the possible cause. However I think that i8042 controller should be responsible for keyboard and you could try booting with i8042.nopnp kernel parametar as BIOS programmers often write dummy interfaces for hardware.

This was meant as just a quick check. I understand that dmesg deals mainly with low-level stuff, like the kernel and drivers (that's why it's kernel.log).
You downgrade xf86- drivers along with the server. I was re-writing this part of my post, but noticed that OP already responded, so I decided to leave it as-is.
Sorry for the confusion.

Re: Xorg 1.9.0 Freezing Up

Alright I am going to try downgrading to 1.8 and post back the results.  Thanks for the responses.  Also, is there an easy way to downgrade the xorg meta package with pacman, or do I have to take every package from the meta package and downgrade those seperately?

Re: Xorg 1.9.0 Freezing Up

xorg is just a guess on my part. If you have a lot of apps that need the newest xorg, the downgrade is going to be painful.

Try booting with 'i8042.nopnp' appended to the kernel line in grub, as suggested by combuster. It will take you only a minute to try it out and is easy as pie. If it works - great, if not, you need to try something else, like downgrading xorg or patching the kernel.
