This error message means that one of the partitions on the disk is in use, so the kernel is refusing to update its internal partition map because this would clobber the in-use filesystems. This is not a kernel bug, it looks like an installer bug.
Please reproduce this error, and attach the contents of /proc/mounts and /proc/swaps. ** Package changed: linux (Ubuntu) => ubiquity (Ubuntu) ** Changed in: ubiquity (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1220165 Title: Error informing the kernel about modificatons Status in “linux-ppc” package in Ubuntu: Confirmed Status in “ubiquity” package in Ubuntu: Incomplete 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.
