Comment(by werner):
A small update: I booted FSO MS3 and let it just sit there completely
idle.
No user input, no SIM card, and no suspend. After about 15-19h, events/0
ran at ~20%.
This time, Xglamo remained silent. So it seems that busy Xglamo is indeed
unrelated.
This might be a continuous interrupt from the S3C MMC hardware. A similar
problem has been observed a while ago with the mainline driver.
Never having observed this problem when using a stack that had SD-SPI at
its bottom also resonates with my hypothesis.
