Comment # 4 on bug 913105 from Takashi Iwai

S3 is a tough problem.  Basically you need to either find out the culprit via
git bisect, or try to trim down the buggy component by reducing the modules or
configurations.

For the latter, set up the system with the reduced modules, i.e. without
graphics (no nouveau, no nvidia, just a text console with nomodeset vga=normal
boot option).  Also, try to drop pm-utils package for possible obsoleted hooks.
In such a reduced system, try the S3 and see whether the kernel can resume
(more or less) stably.
