This is an fbdev problem, I guess.  I'll reassign the report.

OK.
(This is my first bug-report)

Latest working kernel version:2.6.29-rc5
Earliest failing kernel version:not tested

I assume what you mean here is that 2.6.29-rc5 fails, and that you're
not aware of any earlier kernel version which did not fail.

I've tested
2.6.27-14, 2.6.29-rc4 (git-5, git-7), 2.6.29-rc5

all of them fails to s2disk with nvidiafb.

dmesg | grep buf
[    1.651258] Console: switching to colour frame buffer device 160x50
[    1.652466] nvidiafb: PCI nVidia NV1d framebuffer (64MB @ 0xC0000000)

[    1.653320] fb1: VESA VGA frame buffer device


s2disk works ok with:
dmesg | grep buf
[    0.802424] vesafb: framebuffer at 0xc0000000, mapped to 0xf8080000, using

[    0.922487] fb0: VESA VGA frame buffer device

hangs.

Device Drivers -> Graphics support -> Support for frame buffer devices -> []

dmesg | grep buf

in this case everything works OK.
