  "message": "ALSA: memalloc: Try dma_alloc_noncontiguous() at first\n\nThe latest fix for the non-contiguous memalloc helper changed the\nallocation method for a non-IOMMU system to use only the fallback\nallocator.  This should have worked, but it caused a problem sometimes\nwhen too many non-contiguous pages are allocated that can\u0027t be treated\nby HD-audio controller.\n\nAs a quirk workaround, go back to the original strategy: use\ndma_alloc_noncontiguous() at first, and apply the fallback only when\nit fails, but only for non-IOMMU case.\n\nWe\u0027ll need a better fix in the fallback code as well, but this\nworkaround should paper over most cases.\n\nFixes: 9736a325137b (\"ALSA: memalloc: Don\u0027t fall back for SG-buffer with IOMMU\")\nReported-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nLink: https://lore.kernel.org/r/CAHk-\u003dwgSH5ubdvt76gNwa004ooZAEJL_1Q-Fyw5M2FDdqL\u003d\u003ddg@mail.gmail.com\nLink: https://lore.kernel.org/r/20221112084718.3305-1-tiwai@suse.de\nSigned-off-by: Takashi Iwai \u003ctiwai@suse.de\u003e\n",
