For what it's worth, I'm testing suspend-to-ram on Ubuntu 9.10 x86_64I'm using either KDE menu to suspend or hibernate-ram from hibernate-script.
with 2.6.32 final on a T500 and it's been pretty reliable -- I've
suspended by closing the lid at least a dozen times and it hasn't locked
up yet.
I will try to use the lid and see if it makes any difference.
The strange thing is that I tried using rc6 & rc7 and they don't work now
even though they used to, so I now I need to see what broke it.
I mentioned the lid because of BZ #14484 which is only on Intel GMA plus
using the lid switch to trigger suspend. Since neither is relevant to
you it's just a red herring. :)
1. are you using DMAR (VT-d)? I'm not, and I had problems on anotherI disabled DMAR but still no luck.
machine (also Core 2 Duo with GM45 graphics) when I tried suspending
with CONFIG_DMAR=y.
It's getting better but DMAR has still been a little problematic for me
the last few months. Updating to the very latest BIOS does help
sometimes.
2. are you running into http://bugzilla.kernel.org/show_bug.cgi?id=14484I'm using the Radeon GPU so no KMS for me yet.
or a similar problem?
3. (if you have GMA graphics) Are you up to date on the xorg-video-intel
driver? I'm using KMS and xorg-video-intel 2.9.0. 2.8.x is missing
some relevant bugfixes. (Of course if you have ATI graphics then
this isn't relevant.)
Sounds like your Radeon or fglrx driver got updated and broke
suspend/resume.
