Is there an operating system able to run on this machine? If so, run
this operating system and get access to the Ubuntu install's partition
containing /var/log. IOW access the log files by running another
operating system.

If you should have another computer, consider to capture a netconsole
trace.

If it should be a tainted kernel, e.g. special proprietary drivers
should be required for the hardware, excepted of a graphics driver, they
anyway might ignore a bug report.
