SSD on Acer Aspire One Cloudbook 11

Hi guys,
I cannot see the SSD disk on an Acer Aspire One Cloudbook 11.

It's a MMC drive, but sdhci cannot find it. Boot logs are plenty of 
"Controller timeout" (see attached dmesg) and an unfortunate "mmc0: No 
compatible cards found on bus".

Apparently SDHCI can recognize the hardware:
sdhci_pci0_at_pci0:0:16:0: class=0x080501 card=0x106c1025 chip=0x22948086 
rev=0x21 hdr=0x00
     vendor     = 'Intel Corporation'
     class      = base peripheral
     subclass   = SD host controller

Is this a problem with the specific chip? Any suggestion to have this 
working? Thank you

Regards,
