Did hibernate from Gnome with Fn+F12 (hibernate key). Wireless and Bluetooth were both disabled, no external devices were connected and no programs were open at that time. Resumed about half an hour later, system hung with the caps lock LED blinking, otherwise unresponsive.

Caps lock flashing implies a kernel panic, it is worth trying the suspend from VT-1, hit ctrl-alt-f1 and see if you can see the panic messages there. You may need to login on the console and make the font smaller with the command below:

    setfont /usr/share/consolefonts/Uni1-VGA8.psf.gz

I also own a T400 (2765TDG in my case). I haven't tested jaunty yet, but in intrepid, consistently successful suspend/resume and hibernate/resume required disabling one core for about 10 seconds right before sleep and reenabling it right after resuming. I found the suggestion and the script here:

Could this be the culprit again?

Also, could bugs #359728 and #362120 be related or even duplicates of this one?

[zardoz (hyphos)]

I guess bug #350680 is also related.
