Comment 66 for bug 60764

I found out that it was a RAM issue on my machine! I noticed that the workaround of burianek resolved the "Corrupted MAC" messaged, however md5 sums of large files often mismatched after trandfer! Also noticed that ubuntu CD/DVD media verification often turned up a lot of errors on this machine but not on other machines. Made a manual RAM configuration in BIOS setup and all problems seem to be gone.
