$this->bbcode_second_pass_quote('godofdream', '@')ariava
Normally the Oops happend after 1-5 Hours. Without the SLUB-Debugger my oops looked like the one of "yeehaa".
As long as no Freeze happens, there was no error.
I will recompile my kernel with the slub debugger.
@yeeha
could you recompile your kernel with slub-debugger activated?
EDIT:
and there it comes again

, but it took longer until it crashed

I'm afraid this issue seems not to be BFQ-related, as yeehaa could reproduce the nzbget crash with this kind of oops also with the noop scheduler (see
). I'm inclined to believe that this error could be, unfortunately, not related to the oops from the SLUB debugger; on the other hand, the error you found with SLUB debugging enabled would seem to be definitely BFQ-related.
Thank you for your work.
