SD corruption(no suspend and sd_max_clk tested)

[GNUtoo at no-log.org]

Hello,
I've bought a MMBGR04GUACY-NA and its adapter...
but the card produce I/O errors in dmesg...
I was using the kernel from FSO milestone 3
if I remember well it does the same with 2008.8

I've tried lowering sd_max_clk to the 10000000
I've tried increasing the drive strength to 3

I'd really like to try debian...and for this I would need a huge sd-card

What i've done to detect it:
*boot it using the flashed FSO milestone 3 kernel and the 2008.8 userland
*install debian
when I installed debian it stoped with I/O errors
so I changed some sd settings and i restarted installing debian without
rebooting...and it made others I/O errors
