Comment 92 for bug 35174

Same here - suspend to ram (which used to work with the s3_bios setting) no longer works.

Hibernate, which used to (apparently) hibernate OK, but failed to resume, now doesn't even hibernate properly - the fan doesn't turn off, and the moon-shaped "sleep" light flashes continually.

Also, after power cycling during a failed hibernate, the machine no longer boots with that kernel (it stalls on "Mounting root file system...") - I assume it's looking for the hibernate files or something. I had to select an older kernel before I could boot.
