Comment 10 for bug 590201

Serge,

The problem must be related to the hardware. The machine I have the bug
on is a laptop w/ AMD Turion cpu, ATI/AMD chips (RS690, SB600). As you
said it works for you on an Intel laptop, I've managed to try the same VM
image on a HP laptop w/ Intel Core quad, Ubuntu 10.04 fully updated, and
it is working.

Note that the AMD machine still has a Ubuntu 9.04 _not_ updated, and kvm
runs the OpenSolaris VM with that, just not with 10.04 or 10.10; moreover,
VirtualBoxOSE will run the _same_ VM image under 10.04 and 10.10.
So, the problem must be between the hardware and some kernel and/or kvm
that appeared with or shortly after the 10.04 release.

Note also that that since 10.10 there are other problems, such as that display
brightness or pm suspend do not work if booted on main power, but _do_ work
if booted on battery. The kernel has regressed for that hardware.

I should have tried on Intel sooner. Still, it isn't strictly a hardware problem -
the older software worked.
