Well, just for the record, it triggers when you have
scsi devices using elevator=none over blkmq.
And it's not a default/usual configuration.
So, b11g, can you check please if the NixOS kernel is compiled with these flags?
And/or if they have something like:
scsi_mod.use_blk_mq=1
in the boot command line?
Ciao,
