Comment 3 for bug 758384

I have now tried copying the Music directory by FTP. Eventually I start having I/O errors which are logged in syslog.

Here is the log info. All is well after boot, up to the point where the apt daemon shuts down. Then after the FTP is up and running for awhile, there is an "ata2: lost interrupt (Status 0x58)". The system never fully recovers but eventually I manage to get things shut down.

This is a very serious bug for me - a complete show-stopper for using natty... please help!
