[Bug 43961] Re: Power down after shutdown does not work...

[Oliver Brakmann]

This may be too soon to draw conclusions, but I've changed three things on my system since my last comment and I now it shuts down properly more often than not (ie. only every one of ten or so shutdown attempts fails instead of the other way around).
These changes are:
- I moved my system from a single disk to two mirrored ones. (I guess this doesn't have any influence whatsoever)
- I enabled the vesafb framebuffer driver instead of the crappy default one (which produced ugly fonts and flickering on my TFT in text mode)
- I disabled usplash.

Maybe a few people could try the vesafb driver and disable usplash and see whether things improve for them.  My kernel command line is as follows:
root=/dev/md_d0p1 ro raid=part vga=0x305 video=vesafb:ypan,mtrr:3,vremap:4 acpi=power-off quiet
