Missing wd0 on mac

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hello

On an iMac with fusion drive (hard disk and NVME blent by MacOSX into a 
single logical disk), NetBSD seems unsable to detect the hard disk.
I have this in dmesg:

ahcisata0 at pci0 dev 23 function 0: Intel 100 Series SATA (AHCI) (rev. 0x21)
ahcisata0: 64-bit DMA
ahcisata0: AHCI revision 1.31, 1 port, 32 slots, CAP 0xc734ff00<PSC,SSC,PMD,SAM,
ISS=0x3=Gen3,SCLO,SAL,SALP,SNCQ,S64A>
ahcisata0: interrupting at msi1 vec 0
atabus0 at ahcisata0 channel 2

No wd0 shows. drvctl -r or atactl reset do not help. Is it a somehow known 
problem?

This is 9.99.92 from nov 2019. I need to upgrade to see if there is an 
improvement.
