Borislav,

I tested again with 2.6.38 kernel: the system was stressed for several
hours with various activities (compiling, copying data back and forth
from two hard drives, encoding/decoding video streams, etc) but I was
not able to reproduce the problem, so I guess it has been fixed.
If you're interested here's the info I collected with 2.6.38:

I found a similar report on the web, I don't know if this could be related:

Let me know if you have other questions. Regards,

Giorgio Vazzana
