(Get the code!)
Back again. Problem *not* solved after all with the latest daily Natty.
The *live cd* suspends and resumes correctly, but as I just found out opening my laptop which has been asleep all night, the installed system does not.
Black screens for TTYs and X. Blind-typing in TTYs not possible. I can Alt+F7 my way back to X from the black TTYs, and here I can move a mouse cursor around on a black X screen. Power button does not trigger ACPI shutdown, and I must power off the system.
Now I'm back to hinting at the mentioning of the FS in the kernel oops I saw on my previous Kubuntu installation. Because the livecd does not live on a regular fs, it lives on cd + unionfs in mem, right? The kernel oops stated that the origin for the panic was in the fs code.
While the Kubuntu installation had an encrypted swap and lived on btrfs, this Ubuntu installation has unencrypted swap and lives on ext4 (because GRUB wouldn't boot after installing / on btrfs (/boot on ext3)). So while this probably means that it *isn't* a problem with fs code, might it be that whatever the system is trying to do at that point, fs-wise, is the culprit? Like, which filesystem operations run when you resume after suspend?
I'd look there if it were me, anyway ;)
