Does anyone have suspend to RAM (s1, s3) working at all?
My laptop is a 2 year old Toshiba (but not really, meaning it runs a Phoenix BIOS and really is just a toshiba in name only). I use the 2.6.9 gentoo-dev-sources kernel (including swsusp2 support, which works fine for either s4 or s5 hibernate states). According to ACPI on my laptop, it should support all sleep states s0, s1, s2, s3, s4, and s5. Though really, s0, s3 are the only useful suspend to RAM states I believe.
But I've never ever gotten proper standby (suspend to RAM) to work, like when I used to run Windows. swsusp2 hibernate is pretty good, but takes about 20-25 seconds to wake up and about 10-15 seconds to hibernate. Don't get me wrong, this is fine, but sometimes I just wish for some kind of suspend to RAM, which, as many of you know, gets you from sleeping to working in about 3 seconds.
So, does anyone have suspend to RAM working at all?

I'm in the same situation as you. Hibernate works, but not suspend to ram. I've tried on three different lappies with at least four different distros.

Video issues with S3 resume ~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2003-2005, Pavel Machek During S3 resume, hardware needs to be reinitialized. For most devices, this is easy, and kernel driver knows how to do it. Unfortunately there's one exception: video card. Those are usually initialized by BIOS, and kernel does not have enough information to boot video card. (Kernel usually does not even contain video card driver -- vesafb and vgacon are widely used). This is not problem for swsusp, because during swsusp resume, BIOS is run normally so video card is normally initialized. S3 has absolutely no chance of working with SMP/HT. Be sure it to turn it off before testing (swsusp should work ok, OTOH). There are a few types of systems where video works after S3 resume: (1) systems where video state is preserved over S3. (2) systems where it is possible to call the video BIOS during S3 resume. Unfortunately, it is not correct to call the video BIOS at that point, but it happens to work on some machines. Use acpi_sleep=s3_bios. (3) systems that initialize video card into vga text mode and where the BIOS works well enough to be able to set video mode. Use acpi_sleep=s3_mode on these. (4) on some systems s3_bios kicks video into text mode, and acpi_sleep=s3_bios,s3_mode is needed. (5) radeon systems, where X can soft-boot your video card. You'll need a new enough X, and a plain text console (no vesafb or radeonfb). See http://www.doesi.gmxhome.de/linux/tm800s3/s3.html for more information. Alternatively, you should use vbetool (6) instead. (6) other radeon systems, where vbetool is enough to bring system back to life. It needs text console to be working. Do vbetool vbestate save > /tmp/delme; echo 3 > /proc/acpi/sleep; vbetool post; vbetool vbestate restore < /tmp/delme; setfont <whatever>, and your video should work. (7) on some systems, it is possible to boot most of kernel, and then POSTing bios works. Ole Rohne has patch to do just that at http://dev.gentoo.org/~marineam/patch-radeonfb-2.6.11-rc2-mm2. (8) on some systems, you can use the video_post utility mentioned here: http://bugzilla.kernel.org/show_bug.cgi?id=3670. Do echo 3 > /sys/power/state && /usr/sbin/video_post - which will initialize the display in console mode. If you are in X, you can switch to a virtual terminal and back to X using CTRL+ALT+F1 - CTRL+ALT+F7 to get the display working in graphical mode again. Now, if you pass acpi_sleep=something, and it does not work with your bios, you'll get a hard crash during resume. Be careful. Also it is safest to do your experiments with plain old VGA console. The vesafb and radeonfb (etc) drivers have a tendency to crash the machine during resume. You may have a system where none of above works. At that point you either invent another ugly hack that works, or write proper driver for your video card (good luck getting docs :-(). Maybe suspending from X (proper X, knowing your hardware, not XF68_FBcon) might have better chance of working.
