Public bug reported:
Suspend To RAM doesn't work with Sony Vaio TX2 with every Ubuntu I have tested
(Breezy, Dapper and Edgy). I shuts down and the Power LED blinks red instead of
green but after starting again through key press oder power button it never
comes up again. After resume the hard disk led glows permanent for around 30
seconds and then went out and the screen is always dark. Laptop doesn't react
to keys. Only a hard shut down through holding the power button for about three
seconds works.
I have experimented with many acpi-support settings like resetting hard drive,
disabling dma, vbestate restore and so on but nothing helps. Even I have tested
nearly every combination of s2ram without success. Always the same problem.
Of course suspend to ram work under Windows but the interesting thing is that
after suspend resume it sounds/looks like a reboot since the hard disk seems to
reset and some LEDs flashes.
I have searched for a bios update but I haven't found any one on sony homepage.
