Hi,
My custom board have an SD card on SPI SSEL5.
Speed is 20MHz, SPI_MODE_3. The card is a 2G Sandisk micro SD.
The file system is ext3 or vfat, doesn't matter.
I wrote a simple script which fills the card with data. A new directory created in every seconds and textfiles created inside the dir.
The problem is that after 130-160 seconds an exception occures, page allocation failure.
My question is: is it stable for others? What can I do? Any suggestion?

flush the page cache manually with /proc/sys/vm/drop_caches

I tried. Nothing changed but i have more free memory and less allocated buffers.
I did the same test in initramfs and the result is the same. The system hangs before running out of memory.
I'll attach my test script after my summer holiday ended.
