How to report OSD framebuffer bugs?
-----------------------------------
Make sure you read entirely README.realmagichwl instructions at first.

Sanity check
------------
1. How much RAM on the PC?

2. Can you confirm the PC is not equipped with a built-in VGA
board that uses host memory as video memory?

3. Did you properly update:
LILO users: lilo.conf, and run again lilo, and reboot
GRUB users: grub.conf, and reboot

4. Prior to inserting realmagichwl_kernelland.o and
realmagichwl_kernelland_osdbuf.o, was there already a framebuffer
active, for instance the one of the video card you are using?
(look in the logs)

Reporting
---------
Information:
- which distribution
- kernel version; is it a RT modified kernel? (uname -a)
- which video card 
- how many EM84xx devices in the system, and which versions (xcard, harmony...)
- did the bug happen when using a console application, or
a more complex application (direct mapping, or X on fbdev)

I need these files:
- LILO users: lilo.conf, GRUB users: grub.conf
- after fresh reboot, run dmesg >dmesg.output and send dmesg.output
- before any insmod, cat /proc/interrupts >interrupts.output
- before any insmod, cat /proc/pci >pci.output
- complete /var/log/messages excerpt for insmod realmagichwl_kernelland.o
  (cut&paste to realmagichwl_kernelland.log)
- the command line used to insmod realmagichwl_kernelland_osdbuf.o and
  the complete /var/log/messages excerpt about it
  (cut&paste to realmagichwl_kernelland_osdbuf.log)
- complete /var/log/messages excerpt for insmod realmagichwl_kernelland_fb.o
  (cut&paste to realmagichwl_kernelland_fb.log)

To solve the bug, there must be a simple and deterministic way to
reproduce it 100% of the times: how to reproduce the bug?
