Title:
  Error informing the kernel

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  When installing the desktop powerpc image, the installer comes up with
  an error message:

  "Error informing the kernel about modifications to partitino /dev/sda3
  - Device or resource busy.  This means Linuxc won't know about any
  changes you made to /dev/sda3 until you reboot - so you shouldn't
  mount it or use it in any way before rebooting."

  I made no changes.  The installer comes up with this error all on its
  own right before the "Where are you?" screen.
