sdmmc reader not working on 8.0_RC2/amd64

[Benny Siegert <bsiegert%gmail.com@localhost>]

I am trying to use the SD/MMC reader in my PC (Intel NUC), however I
always get the following error:

sdmmc0: sdmmc_mem_enable failed with error 60
sdmmc0: couldn't enable card: 60

60 is probably ETIMEDOUT, no? Any ideas what could be done?

For completeness, here is where the sdmmc attaches to:

sdhc0 at pci2 dev 0 function 0: vendor 1217 product 8621 (rev. 0x01)
sdhc0: interrupting at ioapic0 pin 17
sdhc0: SDHC 4.0, rev 6, SDMA, 50000 kHz, HS SDR50 DDR50 SDR104 HS200
1.8V 3.3V, re-tuning mode 1, 512 byte blocks
sdmmc0 at sdhc0 slot 0
