mmcsd0 / sdhci issues ?

[Mike Tancsa]

Hi All,
	We are hoping to start rolling out the newer PC-Engine's APU2s in the
near future, but am seeing a lot of sporadic disk errors off the SD
cards.  Any idea if this is a driver issue ? BIOS issue ? SD card issue ?

apart from a reboot via watchdog, is there any way to better recover
from this error ?
