In contrast to Dmitry, the problem happens for me even right after reboot, and not only after some uptime. Copied a bunch of files, and checked MD5's - one of them was wrong - so it is probably not a symptom of what you described. p.s. I think the importance of this issue should be raised from "Affects Some People" - since part of this problem is quiet corruption, I assume a lot of people with Intel adapters have corrupted data and do not even know. -- You are receiving this mail because: You are the assignee for the bug.
