On 2GB of memory, everything works fine.

On 4GB of memory writing to disk causes data corruption! The data corruption happen on copying big files (700MB). Before running md5sum, make sure to clean memory by doing memtester with MAX-200MB parameter.

I tried BIOS IDE configuration to be in "Compatible", "Enhanced+RAID", "Enhanced+IDE", "Enhanced+AHCI" settings, but the data corruption persisted.

If I slow down the disk as much as possible (No Multiple sectors transfer, PIO 0, slowests DMA), the data corruption occurs only once per about 2.5 GB.

There is a thread on LKML about similar problem: http://lkml.org/lkml/2007/8/7/433
