Description Michael Buro 2005-12-27 12:07:18 UTC

Most recent kernel where this bug did not occur: S3 never worked for me
Distribution: Fedora Core 4
Hardware Environment: Asus z71v notebook
Software Environment: bios 0210 / gcc-4.0.2 / nvidia driver 8178
Problem Description:

Suspend-to-ram doesn't resume: the machine freezes (black screen) and the
CPU fan runs at highest speed. Under Windows S3 works and the CPU fan also goes
on after S3 resume, but only briefly.

I experimented a lot: suspending from text console, setting polling_frequency to
1, disabling frame buffer devices, passing on acpi_sleep parameters to the
kernel, etc - google produces many pages that give S3 advice ...

No changes whatsoever.


Steps to reproduce: 

hmm, I guess installing FC4 on a z71v and trying to get S3 working ;-)

same with 2.6.22.stable?
Re: video -- any luck with Documentation/power/video.txt workarounds?

I recommend that you try both the open-source driver and the binary from nvidia.

please re-open if this is still a problem in linux-2.6.22.stable or later
