*snort*
The message is caused by
printk(KERN_INFO PREFIX "Please implement %s\n", __func__);
seq_printf(seq, "<TODO>\n");
in acpi_video_bus_ROM_seq_show(), so it's not surprising. Shouldn't spew
to syslog, but other than that it's a non-issue. Stack trace, OTOH, is
something very different; something is trying to generate 2Mb of contents
in a single ->show(). Which is definitely not that one - "<TODO>\n" is
not going to eat that much ;-)
