Workaround : "s2ram --force --acpi_sleep 1 --vbe_mode"
Status : problem is being debugged

I'm inclined to write this one off as general STR weirdness. The problem is reproducible on 2.6.22 if CONFIG_FB is enabled (even if not *used*!), and there is a working workaround that is required on a lot of machines.

This is suboptimal, of course, but it seems to require a pretty deep investigation into the intricacies of this particular platform.

I'm inclined to write this one off as general STR weirdness.

Both suspend-to-ram and suspend-to-disk are broken on this Vaio. Running 2.6.23-rc4.

suspend-to-RAM:

a) sometimes hangs during suspend

b) frequently hangs during resume

c) occasionally acts weird after resume. system requires repeated keypresses to make forward progress.

d) on those occasions where resume-from-RAM _does_ work, it takes much longer to resume than it used to.

suspend-to-disk:

a) always hangs when netconsole-over-e100 is enabled (might have been a 2.6.21->2.6.22 regression).

b) usually hangs during suspend

Apart from suspend-to-disk's a), all of the above are post-2.6.21 regressions.

Can you please close this case. I'm using the workaround and satisfied with it.

2.6.21 was OK, and 2.6.23-rc2 needed a manual workaround?

That's a regression.

Yes, it is. 2.6.21 was OK, but only within a narrow and ill-characterized set of conditions (framebuffer not compiled into the kernel, in particular.) It appears to me that the interaction between STR and video on this system is extremely fragile, to the point that any minor perturbations in the state can break it, and that that is the real underlying problem here.
