Hi.

An update on this:

This was documented in the ChangeLog (not in so many words), and the fix
is a module option:

options snd-hda-intel power_save=0

This one was fixed by adding this on the kernel command-line:

dm_mod.use_blk_mq=0 scsi_mod.use_blk_mq=0

It is possible that "ahci.mobile_lpm_policy=0" helps too, it was
suggested to me as a fix too and I have not yet tested without it, nor
with use_blk_mq in modprobe.d instead of the kernel command-line.
