Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
I'm having some issues with my laptop after the kernel upgrade. During the boot I get the kernel BUG at drivers/media/media-entity.c:346! message. You can see the whole output here: http://pastie.org/2343779.
The loading of Udev rules fails. After that the system boots normally, but it freezes the second I plug in/out the wireless keyboard usb receiver or usb memory stick.

You might want to blacklist uvcvideo. After rebooting most things should work normal.

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
Thanks steffinger. I've blacklisted the uvcvideo module in rc.conf but this doesn't solve the problem. After I restarted the system I found out that uvcvideo module is still being loaded even if I blacklist it

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
Blacklisting in rc.conf is not working any more. You should use /etc/modprobe.d/blacklist.conf instead!!!
Refer to: http://www.archlinux.org/news/changes-t … cklisting/ for further information.

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
I don't think that this is a known bug. Maybe you can file it? What does work for you now and what doesn't? Can you maybe post the output of lsusb? Just for my curiosity.

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
Now I'm not having the issues I head earlier. They were all connected to usb as far as I was aware (usb memory sticks didn't work etc.). Since I blacklisted uvcvideo module my webcam isn't working (obviously). I didn't notice any other issues so far.
Here's my lsusb output:

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
I guess that "Bus 002 Device 003: ID 046d:c52e Logitech, Inc." should be your camera or are you using Logitech usb mouse/keyboard? If you need your webcam, you could try to use other drivers than uvcvideo. https://wiki.archlinux.org/index.php/Webcam gives some hints. Would be interesting if this can resolve the problem.
From my lsusb i can't see which one is my camera, so I can't really try it myself.

Hey steffinger,
Bus 002 Device 003: ID 046d:c52e Logitech, Inc. is my wireless mouse/keyboard, so I'm not able to determine what is my webcamera as well...

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
Thanks Caspian,
I think we can do nothing but hope, that this will be corrected with kernel 3.1. I'm a bit busy these days, but I will soon try to check http://www.ideasonboard.org/uvc/ if they are informed about the problem so they can fix it. I doubt that it is a problem of the arch packages.
Any other thoughts about this?

Steffinger,
I don't know what else can we do. The issue is still here with the latest (3.0.2-1) kernel package...

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
I know this is not a solution to the real problem, but your bug is subtle, because I have no problem with uvcvideo on 3.0.1:
$ grep -i uvc /var/log/dmesg.log

first I need to say, that the update for 3.0.3 which came in yesterday changes nothing. For Leonid I removed uvcvideo from my blacklist to show you my dmesg.log. Here comes the interesting part:

But in my lsusb you can see the following:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 001 Device 004: ID 0a5c:219c Broadcom Corp. The Realtek thing should be my wireless LAN device. I think. I'm not to good with this.
My vendor says that my Camera is as follows: Suyin / Lite-on / Primax/ Dmax and as a driver the native windows driver should do, it says.
So it's kind of complicated as far as I can see because this is not in lsusb.
One remarkable thing is, as I said before, that everything worked with kernel 2.6.39.
I tried to find out some things about the makers of uvcvideo, but they don't give a lot of information. So if this should go upstream I need a bit help.
@Caspian: What does your vendor say about the camera?

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
Well, this kinda proves my point...
@steffinger:
The ID in the error message, "0bda:58e8", is realtec according to lsusb (notice that in my previous post the ID in dmesg.log is Chicony which is correct). Moreover, the tainted line says "C", which means that staging drivers are loaded. The uvcvideo module is linked to the brmc* staging drivers... wtf?
@Caspian:
Again, 13d3:5710 (from dmesg.log) points to your network adapter (IMC networks).
Do you guys have NICs sitting on the USB? If so, I would unload the corresponding network adapter modules instead of uvcvideo.

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
Sorry if I am a bit slow understanding your point. But I try to answer your points as good as possible. You ask whether we have our network interface controller connected on the usb. Does this mean, you want to know if this NIC is external? In this case I can deny your question. I'm using a laptop with integrated NIC.
Further you suggested to unload the corresponding network adapter modules. So i unloaded (which resulted in a crash, so i blacklisted them) following modules:
mac80211 cfg80211 brcmsmac brcmutil crc_ccitt rfkill bluetooth
But this changed nothing. My dmesg.log ist still pretty similar:

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
All I am saying is that the line
uvcvideo: Found UVC 1.00 device USB Camera (0bda:58e8)contains the ID (0bda:58e8) which does not correspond to a webcam, unless this is a realtec webcam. This is the reason why I think it's not a problem of uvcvideo but kernel/bios. Otherwise it is quite strange to see NICs in the output of lsusb...
You could try to look at the verbose lsusb output, and install usbutils 004 from [testing].

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
Hi Leonid,
first of all thank you for your help. I think you are very right. It don't think it's mainly a problem caused by uvcvideo, but I also do not think it's totally innocent. Here are some of my reasons: To make some videocalls I installed ubuntu 11.04 which is pretty much of a pain, but it is running kernel 2.6.38. The output of lsusb stays the same but the webcam works. In the dmesg log it looks like this:

(Bus Powered)So for me one strange thing is, why the video device is listed as a Realtek device. Apparently because of the VID. But why does the vendor ID say it's Realtek? I never heard of any Realtek webcams and as I said before, the producer of my laptop says it's a Suyin camera.
The other strange thing is like before, why does it work with older kernels (with similar conditions) but not with 3.0?
Not to forget: usbutils 004 sadly doesn't change anything for me.
Finally I think that there isn't a connection between the so-called realtek-device in my lsusb and my NIC. In lspci I can see another Realtek device which really is my NIC. So I think it's just by accident, that it's called Realtek.

Re: Kernel 3.0 upgrade - Udev rules problem (kernel BUG at drivers/media/)
No problem 
But after some google search, I stumbled upon this http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=637740 which seems related t oyour problem. Apparently, upstream is working on it already...
