Title:
  Copying files to usb stick slows down to a crawl progressively

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Copying 1gig of data starts fast at 12MB/sec but after 200MB have been
  copied is starts to slow down. It report 2MB/sec but it is also very
  stop start in nature, takes ages to finish the copy. This is
  repeatable as it happens the same every time. The device is labeled as
  a Disgo 4gig usb stick and is formatted ntfs although same happens
  with ext4. I'm installing the mainline kernel mainline/v2.6.35-rc1 to
  see if any different. Will report back
