[ltp] Re: Suspend-to-RAM on Thinkpad R50e (partial success)

Hi Pawel,

it seems really strange that this should work. From your kernel config I ca=
n=20
see that you are using the VESA framebuffer by default. The intelfb cannot =
be=20
loaded "on top" since you already got a framebuffer device.
As I am getting the same error you got without using intelfb at all, I don'=
t=20
think it is intelfb related.
I did try it your way anyways, but I got the same error. I really wonder wh=
at=20
makes it work for you (even though only once). Can you send me your dmesg=20
output (`dmesg > dmesg.txt`)? Maybe I can find something.

Cheers,
Mo
