Only instance Standard_F32s_v2 (not reproducible on Standard_B4ms) and only Hirsute v5.11 (not reproducible Focal v5.8). I could not find the cause of failure.

Reproduced also on QEMU with 32 or 64 CPUs, but not with 31 CPUs (focal/hwe-5.11 and mainline v5.13). Fixed by branch 'delalloc-shrink' of https://github.com/josefbacik/linux.
