Probably this is due to the "flush procedure" that from time to time is going to sync the filesystem on the flash device. But... how about the io/scheduler ? Reproducible: Always Steps to Reproduce: 1. having 3 files of 1 GB each 2. from terminal: copy 1.sample 2.sample 3.sample /media/FLASHDISK 3. use desktop, browse internet, etc. while copying -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
