You pointed to the build I did this morning, which definitely doesn't include the commit you mentioned. Are you saying you took this morning's build and applied the patch yourself?

So of course it isn't in 3.9.0-0.rc0.git7.1.fc19.x86_64. ;) Building particular module groups(skge & Co.) rather than build an entire kernel tree isn't big deal, likewise. You know that better than me. ;) The real question is whether someone will help squeeze this bug.

I want just know if I could reproduce that AF9015 error message or was it just warning. Is it something I have to fix for Kernel 3.10 or earlier. I am running Fedora 17 AMD64 and could surely compile any Kernel needed. regards Antti -- http://palosaari.fi/ ^ permalink raw reply [flat|nested] 5+ messages in thread

Kernel hacking ---> Enable debugging of DMA-API usage There was rather many DVB USB drivers using USB bulk buffers from the stack. I will fix at least some of those, lets say for 3.10. regards Antti -- http://palosaari.fi/ ^ permalink raw reply [flat|nested] 5+ messages in thread
