Hello Andrew,

When I had the problem , about 3 days ago , I've  boot an older current , fscked the (very) corrupted file systems and then I 've built the latest current , which I have about 3 or 4 days now.It seemed to work well without any problems with my SATA disks , but there wasn't any heavy I/O to the disks to let me know.
	Today , I 've tried to concatenate 2 dvd images , about 2 G each and I saw again those READ_DMA errors for my SATA disk, hearing it spinning, and my whole system stuck .Now again , the same scenario , I've boot my old working current (and I won't try any heavy I/O at all :-P ) . 
	Is something new commited and breaks SATA?

For my system ( dmesg | grep -i sata ) :
