Some succes with 2.6.11

[Mark H. <Mar...@xs...>]

Hi,


As mentioned earlier, I am trying to get my system up to a more recent
ruby version, so I've tried some of the recently posted patches with
varying results.

1) vanilla 2.6.11 with Aivils 2.6.11-rc4-ruby patch:
- currently working with dual X sessions, very workable
for me :-), but no framebuffer consoles :-(

2) 2.6.11-mm1 with Zoltans 2.6.11-mm1 patch:
- working dual framebuffers; but crash as soon as I start X or when
I switch virtual console. Not workable :-(
(crashes posted earlier)

3) Recently posted (by Aivils) 2.6.11-mm2 with Zoltans 2.6.11-mm2-ruby patch 
(http://www.ltn.lv/~aivils/files/ruby-2.6.11-mm2-2.diff.bz2):
- working dual framebuffers; works great as long as I remain in console
mode :-), but no X :-(
(kernel oops attached at the end of this mail, although at first look it
does not seem ruby, but usb related... any ideas?)

All this is with a Gentoo xorg-6.8.2 system using a set of matrox
cards (G550AGP & G450PCI), using xorg mga driver with matrox HALlib.

So, I'm now using solution 1, since X is what I use the most, but ideally
I would like to see the good results of 1) and 3) combined :-).

Thanks for the good work guys!


Mark.
