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.

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.

Michal,

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

Thanks,

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.

Any progress here?

I see you have a thinkpad, so with right console loglevel, you should
be able to see the messages just after boot...? Where does it really
hang

                              [    0.955389] Back to C!
                              [    0.389803] PM: Writing back config

                              [    0.389814] PCI: Setting latency

Is it here?
