Created attachment 880762 [details] [PATCH] jme: Fix DMA unmap warning The jme driver forgot to check the return status from pci_map_page in its tx path, causing a dma api warning on unmap. Easy fix, just do the check and augment the tx path to tell the stack that the driver is busy so we re-queue the frame. Signed-off-by: Neil Horman <nhorman> CC: Guo-Fu Tseng <cooldavid> CC: "David S.

http://koji.fedoraproject.org/koji/taskinfo?taskID=6692994 This is a test build of an f19 kernel with the above patch applied. Please test it out and let me know if it solves the problem at hand. Thanks!
Hmmmm .... am I correct that this would require me to do a kernel build? I'm happy to try, if I could have a pointer to the newbie's guide to building from the Fedora buildsystem.
No, the kernel build was in the url above. Do you have any feedback on the build?
Sorry, no.
ok, here you go, new build, please test it and confirm that it fixes the problem http://koji.fedoraproject.org/koji/taskinfo?taskID=6790857
Problem appears to have been resolved. Thanks.
