dmesg output

I have now installed F18. With the default kernel that cames with the DVD (3.6.10-4.fc18.i686.PAE), my TV card works fine.

If I update and boot kernel 3.7.5-201.fc18.i686.PAE, then it's the same like on F18.

So it's not only related to F17! 


I attached the dmesg output that appears, when I start kaffeine. It's the same like on F17 (only the versions differ).

Today I got a kernel update. Problem is still there with the new kernel:

This problem doesn't seem to be related to kaffeine or to the DVB driver. Instead, I suspect that your GPU driver is allocating too much memory with vmalloc.

As the above message says, you need to boot your kernel with a "vmalloc=" parameter on it.

So, you need to pass it via your /boot/grub2/grub.cfg for your booted kernel to add a new vmalloc size there. For example, here I use a virtual desktop of 4880 x 1080 x 32 bits. So, I need a very big vmalloc size for my GPU:

	linux /vmlinuz-3.3.7-1.fc17.x86_64 ro root=/dev/root ... vmalloc=536870912

You could try a smaller value than that, like 256MB (256*1024*1024):
        vmalloc = 268435456

It maybe sounds a bit weird: Until yesterday, the only working kernel (without modifying the 'linux' line in grub.conf) was the shipped one (3.6.10-4.fc18.i686.PAE).

Then today, after your comment, I tried again with the latest kernel (3.7.6-201.fc18.i686.PAE): Device not found and the messages in dmesg. So problem is still there.

Then I add your 'vmalloc = 268435456' to the linux line for 3.7.6-201.fc18.i686.PAE in grub.cfg and rebootet. Problem was gone. I rebootet twice more and checked. Worked both times.

But then I wanted to re-check and removed the 'vmalloc = 268435456' line from 3.7.6-201.fc18.i686.PAE again and rebooted. But it still works! Also the 3.7.5-201.fc18.i686.PAE kernel, where I haven't temporary added the 'vmalloc' part, works now!?

The only thing that changed, before I start with your hint, was applying the latest updates:
Feb 11 18:25:51 Updated: selinux-policy-3.11.1-76.fc18.noarch
Feb 11 18:25:52 Updated: selinux-policy-targeted-3.11.1-76.fc18.noarch
Feb 11 18:25:54 Updated: selinux-policy-devel-3.11.1-76.fc18.noarch
Feb 11 18:25:56 Updated: selinux-policy-doc-3.11.1-76.fc18.noarch
Feb 11 18:25:56 Updated: xorg-x11-drv-synaptics-1.6.3-1.fc18.i686
I haven't rebootet after installing them and rechecked only with this updates. But I'm not sure, if this was anything that could fix this issue.



I'll recheck it during the next days and give another feedback then.

25 minutes after my last post: Device not found - same problem (without the 'vmalloc' entry). Then I reboot (still again without the 'vmalloc' entry) and directly opened kaffeine. And TV works.

I have no more idea on that...

Are you still seeing this with the 3.9.4 kernel in updates-testing?

Sorry. I can't say, if the problem is still existing.

I had so massive problems with the DVB card since F18 (system hangs 95% on shutdown, this bug, etc.). And because of that, I finally removed the card and sold it.

Sorry to hear that.  Without having someone for recreate and testing, we'll have to close this out.
