It should be noted that sda3 is the only partition we seem to successfully mount during probing, and that its neibour sda4 which shares a boundary with it is also potentially active as swap:
Sep 3 09:48:46 lubuntu kernel: [ 314.598101] EXT4-fs (sda3): mounted filesystem with ordered data mode. Opts: (null) Sep 3 09:48:46 lubuntu 40lsb: result: /dev/sda3:Ubuntu Saucy Salamander (development branch) (13.10):Ubuntu:linux [...] Sep 3 09:45:18 lubuntu kernel: [ 94.421151] Adding 2439064k swap on /dev/sda4. Priority:-1 extents:1 across:2439064k FS Sep 3 09:48:46 lubuntu os-prober: debug: /dev/sda4: is active swap We should get into this situation and try and activate the emergency holographic shell and see which partitions are actually active and why. As if they are active then the kernel would correctly prevent their modification. -- 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” package in Ubuntu: Confirmed Status in “linux-ppc” package in Ubuntu: Confirmed 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.
