Ubuntu 7.10 Gusty Beta: REGRESSION: Laptop won't hibernate (but crashes)

[Swâmi Petaramesh]

Hi,

My laptop (Acer Aspire 3104 WLMi) was hibernating to disk, and waking up, perfectly good with 7.04 Feisty Fawn - so well that I was actually surprised - but, since I upgraded to Gutsy 7.10 beta, it doesn't work anymore:

- When trying to hibernate laptop, I immediately get a black screen with a blinking cursor at the top-left corner, and nothing else happens ;
- At this point, the system doesn't seem to be hanged : I can switch between text consoles using [Alt]-[Fn]
- If I switch to the X11 console ([Alt]-[F7]), then I get a completely black screen, and from there on the system is completely hanged : Keyboard doesn't respond anymore, "caps/num lock" leds don't react, no disk activity, "MagicSysRq" keys not answering, no way to get out of there but killing power.

Annoying :-(

I will add to this one that I tested this several times and it "consistently crashes".

When I ask to hibernate and get a black screen with a blinking cursor, after a while of "nothing happening" I cant shift between text-mode terminals, but can't login : getty is probably already dead. Can't do anything but shift between consoles, event the "Magic SysRq" keys don't work anymore. If shifting to [Alt-F7], X display, I get a completely black screen (no cursor anymore) and from then on everything's dead, can't do anything but kill power.

Latest "RC" updates didn't bring any improvement on this.

Since I submitted this bug report 11 days ago and it didn't get no attention so far, I found in Gutsy's release notes this bug : https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.22/+bug/121653 that seems to cover the same issue.

There's a good probability that this bug report is then a duplicate, even though I don't see the prblem appearing only for "suspend to RAM" but as well for "hibernate to disk".

Having a laptop that won't suspend nor hibernate since its distro was "upgraded" is something I feel like a painful downgrade...
