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

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 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.

Interesting, you have two framebuffers running on a single card. Does the s2disk works for you if you select nvidiafb and turn off vesa framebuffer?

Can you post the same lines for the latest working kernel with both vesa and nvidia framebuffers selected?

Regards,
Krzysztof
