Failure comes from test that sanity checks all /proc files by doing 1k read from each. There are couple issues it hits wrt. snd_hda_*. Example reproducer: dd if=3D/sys/kernel/debug/regmap/hdaudioC0D3-hdaudio/access of=3Dout.txt = count=3D1 bs=3D1024 iflag=3Dnonblock It's slow and triggers soft lockups [1]. And it also requires lot of memory, triggering OOMs on smaller VMs: 0x0000000024f0437b-0x000000001a32b1c8 1073745920 seq_read+0x131/0x400 pages= =3D262144 vmalloc vpages N0=3D262144 I'm leaning towards skipping all regmap entries in this test.
