Description of problem:
/var/log/messages is flooded by:
kernel: saa7134_alsa: saa7134_alsa_dma_map: saa7134_alsa_map_sg failed
kernel: nommu_map_sg: overflow 17d31e000+4096 of device mask ffffffff
Version-Release number of selected component (if applicable):
since upgrade from kernel 4.11.12-300 to 4.12.5-300
On evevry boot
Steps to Reproduce:
Yes, I also had this problem.
I have forbidden loading of the module saa7134_alsa - the system works, but there is no sound in the TVTime.
We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. The kernel moves very fast so bugs may get fixed as part of a kernel update. Due to this, we are doing a mass bug update across all of the Fedora 26 kernel bugs.
Fedora 26 has now been rebased to 4.15.4-200.fc26. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
If you have moved on to Fedora 27, and are still experiencing this issue, please change the version to Fedora 27.
If you experience different issues, please open a new bug report for those.
I have also blacklist'ed saa7134_alsa (which had not bad effect)
and I'm using kernel-4.15.9-300.fc27.x86_64 now.
Since people just have the module blacklisted, I'm going to close the bug for now. Feel free to reopne the bug if it's still present on 4.15 or later.
