I got the errors indicated below. Only one time at the moment. The system is F10 x86_64. I didnt' get any application error from a user point of view. Actually in latest times I got some files downloaded from browser without giving error but indeed not correctly (after md5sum). Donna if caused by browser bug itself or disk,,,, And quite often firefox segfaults.... I also got a view at the page http://ata.wiki.kernel.org/index.php/Libata_error_messages but I'm not sure of the eventual gravity.... any hints?
