For what it's worth, I'm testing suspend-to-ram on Ubuntu 9.10 x86_64 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. Things to check: 1. are you using DMAR (VT-d)? I'm not, and I had problems on another machine (also Core 2 Duo with GM45 graphics) when I tried suspending with CONFIG_DMAR=y. 2. are you running into http://bugzilla.kernel.org/show_bug.cgi?id=14484 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.) -andy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
