The related email: https://lists.ubuntu.com/archives/kernel- team/2016-January/067683.html The commit message does mention collateral damage: "In effect, this precludes devices that can only DMA from memory addresses below 16MB". Indeed we already have a complaint about a sound card that doesn't work as of kernel 4.4-rc8. If CONFIG_ZONE_DEVICE is enabled, then CONFIG_ZONE_DMA is forced to disabled, which in turn forces these devices, all are sound cards, and their derivative devices, to be disabled: Avance Logic ALS300/ALS300+ ALi M5451 PCI Audio Controller Aztech AZF3328 / PCI168 Emu10k1 (SB Live!, Audigy, E-mu APS) Emu10k1X (Dell OEM Version) ESS ES1938/1946/1969 (Solo-1) ESS ES1968/1978 (Maestro-1/2/2E) ICEnsemble ICE1712 (Envy24) ESS Allegro/Maestro3 S3 SonicVibes Trident 4D-Wave DX/NX; SiS 7018. References: linux/mm/Kconfig; linux/sound/pci/Kconfig One test done (suggested by apw on IRC) was to remove the dependency of ZONE_DEVICE on !ZONE_DMA, but that causes: "#error ZONES_SHIFT -- too many zones configured adjust calculation", as apw predicted. In a mindless way, I tried to allow more zones in linux/include/linux/page-flags-layout.h, but that caused a bunch of "shifting by too many bits type errors. Anyway it seems that MAX_NR_ZONES is, at least partially, hard coded to 4 in some array definitions and such. Please do not ask me to do "apport-collect" for this bug report as it is not needed, nor relevant.
