	You can ;-)

	It's a RC_1:

legendre# uname -a
NetBSD legendre.systella.fr 10.0_RC1 NetBSD 10.0_RC1 (CUSTOM) #10: Thu 
Dec 21 09:51:28 CET 2023 
root%legendre.systella.fr@localhost:/usr/src/netbsd-10/obj/sys/arch/amd64/compile/CUSTOM 
amd64
and tree was updated juste before building system.

	I have to add that after raid is successfully rebuilt, system is 
stable. I don't remember last time I have rebuilt this volume.

	I only use raidframe on regular sata interface. Motherboard is an Asus 
Z97Q (if I remember):

legendre# lspci | grep SATA
00:1f.2 SATA controller: Intel Corporation 9 Series Chipset Family SATA 
Controller [AHCI Mode]
08:00.0 SATA controller: Marvell Technology Group Ltd. 88SE9120 SATA 
6Gb/s Controller (rev 12)

	Raid0 and raid1 are connected to 00:1f.2 (wd2 to wd6).

	Best regards,

	JB
