dmesg flood

I found this in my dmesg: http://pastebin.com/50rrbZrp
Is this normal?


xbian@xbian ~ $ cat /etc/xbian_revision

Certainly doesn't look normal.

Has this always happened or just started? What has happen just before it started happening? Upgrade, installation?

Are you OC passed Xbian?

Try changing smsc95xx.turbo_mode=N in cmdline.txt and see if that improves it.

I think it started after I set up flexget and transmission to automatically download movies and tv series. But I'm not sure, it's been a while since I checked dmesg.
I don't understant what OC mean...

What is used smsc95xx.turbo_mode=Y for? What will change if I set it to N?

[IriDium]

OC = Overclocking

The errors are related to memory, so changing to N might improve things - it's not a permanent solution, more a debug.

If it works, then maybe Flexget or Transmission are requesting large packets.

It may well be a case of reflashing, checking dmesg (Always a good idea everyday) installing Flexget, check, install Transmission and check again.

I've just noticed that you are on Beta2 - why did you not put this in the Beta2 post?

These messages are from a broken/failing kernel. Try to reinstall the kernel package.

[effemmeffe]

[strike]can I do that via xbian-config?[/strike]
done with apt-get --reinstall
let see if it works.

reinstalled xbian-package-kernel, put back smsc95xx.turbo_mode=Y, reboot:

Did you load any specific modules?

Not that I am aware of.
I installed Transmission anf flexget ad described here: http://www.raspberrypi.org/phpBB3/viewtopic.php?t=47084

How do I check?

[IriDium]

1) Did you try my suggestion? Try changing smsc95xx.turbo_mode=N in cmdline.txt and see if that improves it.
2) Change gpu_mem_512=256 to 128
3) Reflash checking dmesg install Flexget, check, install Transmission and check again.

Yes, sorry.
1) I tried and it seems to reduce the problem, but I still get some messages.
2) I will try.
3) I'd like not to, don't have much spare time and it took me a while to have it working... I'll see if changing gpu memory works.[/term]

@effemmeffe

the messages you get are related to a system under full load, with high IO on disks and specially network.

this messages are more or less not important, only the reasons to them are hidden deep in kernel and target of continual improvement by RPI kernel team and others since the RPI exists.

currently (with 3.10.y) there should be no effect on system/user. this is probably just info to devs…

I suppose that the heavy load is due to flexget retriving informations from the net and transmission downloading a bunch of videos, I have a limit of 5 parallel downloads and the destination is the external usb disk.
If those are not errors or indication of a problem I can ignore them, even if it would be better to turn them off.
I'll live with them.
Thanks.
