Problem with internal cardreader in NUC5 and 128GB microSDXC

Hi!

NetBSD localhost 9.0_STABLE NetBSD 9.0_STABLE (GENERIC) #0: Sun Jun 21 10:41:59 UTC 2020  mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/amd64/compile/GENERIC amd64

Hardware: Intel NUC5PPYH (SoC Intel N3700; this is model of 2015 year), latest 2020 year Bios.

Problem with NetBSD 9-STABLE & internal NUC5 cardreader & MicroSDXC 128GB SanDisk Ultra (via adapter). On boot errors are printed. NetBSD 9 and this cardreader in NUC5 successfully works with MicroSDHC cards 32 GB, but does not works with 128 GB cards. All OK with this 128GB SanDisk Ultra card and NUC5 cardreader, because FreeBSD successfully works with this PC, cardreader and card.

The workaround: use external SanDisk MicroSD -> USB cardreader after that NetBSD 9-STABLE successfully works with this card as USB flash stick.

Does NetBSD 9.0 supports SDXC internal cardreaders and 128GB MicroSDXC cards or only SDHC max 32GB? Is it possible to solve the problem at next versions of NetBSD 9-STABLE and -current?

The errors on internal cardreader and 128GB card on boot:

sdhc0: cmd index error
sdhc0: cmd crc error
sdhc0: auto_cmd12 error
sdhc0: data end bit error
sdhc0: data crc error
..
ld0a: error reading ... retrying
