I searched on google but every post there was different. The first said the message can be ignored the second said that it is a "dangerous" error and the third said that he dont know where the error comes from. On FC3 i get this: Fedora Core release 3 (Heidelberg) Kernel \r on an \m /dev/sda: Timing cached reads: 4048 MB in 2.00 seconds = 2026.33 MB/sec Timing buffered disk reads: 164 MB in 3.01 seconds = 54.57 MB/sec Also strange is that the Machine gets a high load when i copy or tar something. That does not happen on other Machines too -----Ursprüngliche Nachricht----- Von: fedora-list-bounces@xxxxxxxxxx [mailto:fedora-list-bounces@xxxxxxxxxx] Im Auftrag von Mogens Kjaer Gesendet: Mittwoch, 2.

A few seconds with google would have told you that the error message can be ignored. What speed do you get on FC3?
