Yes, so do I.

Let me, maybe, describe, what both the VM and the server have in common:

1. have 4 CPUs
2. are EFI-based
3. use blk-mq with BFQ scheduler (it is set up via udev rule during
4. have zswap enabled
5. have 2 SATA disks with RAID10 on top of it (layout f2)
6. have LUKS on top of the RAID, and LVM on top of the LUKS

VM has machine type "q35", BTW.

Do you think something of what's mentioned above is relevant for the
code path in question?
