Screenshot from HTML output of `bootgraph.py`

`bootgraph.py` [1][2] gives the result below.

> radeon_init: start=14003.930, end=16336.770, length(w/o overhead)=2278.062 ms, return=0

Most of the time is spent in `local_pci_probe (2322.816 ms @ 14.013451)`.

Set it up, using `sudo ./bootgraph.py -f -fstat -maxdepth 10 -manual` to see
what to add to `/boot/grub/grub.cfg`. Then reboot, and execute `sudo
./bootgraph.py -f -fstat -maxdepth 10`.

If your system is powerful enough, you can use a higher maximum depth. I didn’t
get around how `-cgfilter` works to get smaller HTML files.
