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.
