That's good. I hope crashes ended

I compiled the latest version and updated the PKGBUILD so it's easy for you guys to build before it's released. Just make sure to install "base-devel"

$this->bbcode_second_pass_quote('godofdream', '3') Crashes with bfq scheduler, each of them caused nzbget to freeze.
I ran a 2 hour test with cfq without any crashes.

@mooman
both version cause the same crashes.
But I'm not using the pkgbuild i compiled nzbget myself and, i'm using a 3.7.4 Kernel with the same patches and config as the archlinux 3.7.4-kirkwood kernel.

I'm trying to compile 3.8.2 with the newer bfq patch, maybe the crashes are gone.

Thanks for the update. Glad to hear that.

Hello,

I'm Arianna Avanzini from the bfq-iosched mailing list. I'm not sure whether you're reading the discussion on the BFQ Google Group, so I'm writing directly here (I hope I'm not violating any rule of this forum).

godofdream, if you're still experiencing the issue you reported and you have some spare time, could you please test the patch available here?. It should apply without rejects both with patch -p1 or git am on your linux-kirkwood kernel with BFQ-v6 or BFQ-v5r1; you should be able to compile it without warnings.

If you want, please let us know about any issue you may encounter.

[moonman]

Hello Arianna,

Thank you for updating us with the patch.

I'm currently rebuilding the kernel with the patch included and will post it here shortly. It would be nice if people could try it out with nzbget that's known to have problems. Maybe new version has changed its behavior and doesn't cause oops, but the problem is still present.

Arianna, is this an experimental patch or will it be included in the future official BFQ release?

[ariava]

Hi moonman,

thank you very much for your help and for the prompt reply.

The suggested patch was proposed about a week ago in the bfq-iosched group (thread here). It fixes an issue we observed on our machines and we believe to be the same you experienced.
I believe Paolo Valente will however merge the patch into the next BFQ official release.
