patch to do dma error checking

here you go, please build this patch into your kernel and confirm this patch fixes your problem.


Comment 3 Leslie Satenstein 2013-04-22 18:53:24 UTC
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.

Comment 4 Neil Horman 2013-04-22 19:55:18 UTC
Um, ok, you have all the tools you need to build your own kernel, but here you go:

Comment 5 Neil Horman 2013-05-08 20:04:13 UTC
Ping, any feedback on this?

Comment 6 Neil Horman 2013-06-13 19:13:43 UTC
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?

Comment 7 Neil Horman 2013-06-26 14:35:17 UTC
ping, I'm closing this if I don't get any feedback here
