I used a USB stick downloaded on a Ubuntu machine and installed using the default Ubuntu tool (usb-creator-gtk).
There are no I/O errors in the log, but the base-installer / in-target components fail to run and exit with errors. But if you cannot repeat this by selecting the LVM options, then I guess it must be something related to drivers on that IBM hardware or something.
