Linux Hibernation
I thought I should talk about hibernation on Linux...
I recently decided to give Software Suspend 2, codenamed swsusp2, and the hibernate script a try. My goal being to power off my desktop PC and quickly retrieve my session when powering it back on.
So I downloaded a 2.6.12.3 Linux kernel, applied version 2.1.9.9 of the Software Suspend 2 set of patches, and compiled the whole thing. Then I diligently followed the instructions provided in the HOWTO to set the swsusp2-enabled kernel.
My first suspend attempt didn't work because I haden't installed a recent enough version of the hibernate Debian package. (I had downloaded it from a debian/testing mirror.) So, as indicated in the HOWTO, I added the line deb http://cp.yi.org/apt/hibernate ./ to my sources.list file, and downloaded the hibernate package from there.
This time suspend worked, but resume failed badly with a kernel oops. I figured out that the oops was due to Preempt The Big Kernel Lock (CONFIG_PREEMPT_BKL) configured in my kernel. Re-building the kernel without it resolved the problem.
The only remaining issue I have is with the keyboard: from time to time it comes back frozen after resume. This problem is known, and apparently not yet resolved.
