Created attachment 738607 [details] patch to do dma error checking here you go, please build this patch into your kernel and confirm this patch fixes your problem. Thanks!
I cant help you unless you can give me a link to the new kernel. I am, as an end-user, testing F19 with my two hardware systems. (One system for 32bit,one for 64bit). CPUs are Intel I925 and E7300 (both dual core) If I have a download link, I will replace existing kernel that you patched.
Um, ok, you have all the tools you need to build your own kernel, but here you go: http://koji.fedoraproject.org/koji/taskinfo?taskID=5289865
Ping, any feedback on this?
ping, This needs to be pushed upstream, and I'd like to get some testing feedback on it first, as I dont' have this hardware. Are your issues resolved with the kernel I provided you?
ping, I'm closing this if I don't get any feedback here
