That's good information....<br>
<br>
I'll post a confirmation when I try the patch tonight if it works.<br>

That's probably not enough, since a couple of kernel modules (e.g. USB)
tend to get into the way at suspend time, or the screen stays garbled at
time. There is a example script at
<a class="moz-txt-link-freetext" href="http://thinkwiki.org/wiki/How_to_configure_acpid">http://thinkwiki.org/wiki/How_to_configure_acpid</a> that you might extend
to your needs.

BTW, I'm still using "echo -n 3 &gt; /proc/acpi/sleep" via the
hibernate.conf settings, but I have to confess that I haven't tried
the /sys/power/state way in a while.

Otherwise suspend to RAM works very reliable for me, not a single crash
with kernel 2.6.14 and the 3rd patch from the Wiki.
