Sony VAIO (VGN-BX560B) fails to suspend

[Matthias]

Sony VAIO with latest BIOS (R0190X5) fails to suspend and hibernate. When attempting it switches away from X, all three keyboard status lights flash once, then all I'm left with is a blinking cursor at the top left of the screen. Fan still runs and all lights still look like they did when the systems was running.

reset is needed to make the system useful again.

hibernate does recover the state.

the issue seems to be that the power is not turned off and fans, screen and possibly other things are still running.

I followed the suggestions at http://people.freedesktop.org/~hughsient/quirk/quirk-suspend-advanced.html and non of the kernel options produced much different results. vga=792 seemed to turn the display off but the fan was still running.

This was the case for Hardy and now Intrepid. It's worth noting that at one point with kernel 2.6.8 suspend to ram worked just fine.

Just tried the suspend again after upgrade to oneric ocelot and kernal version 3.0.0-12-generic. The issue still exists on that kernel.
