That's strange, since FreeBSD 4.8 doesn't know about hibernation. It just
thinks it's being put to sleep. The BIOS knows to copy things to the
hibernation partition and shut down after the OS has gone to sleep.
You didn't answer any of the following questions in your original message,
so:
1. Did you put
options CPU_SUSP_HALT
and
device apm0
into your custom kernel config?
2. Did you put all of:
apm_enable="YES"
apmd_enable="YES"
apmd_flags="-f /usr/local/etc/apmd.conf"
into /etc/rc.conf (changing the path name to the location of your
customized apmd configuration file)?
3. Did you customize apmd.conf to incorporate
apm_event SUSPENDREQ, USERSUSPENDREQ {
exec "/usr/local/etc/rc.suspend";
}
apm_event NORMRESUME, CRITRESUME, STANDBYRESUME {
exec "/usr/local/etc/rc.resume";
}
or the rough equivalent, to invoke your customized suspend and
resume scripts?
4. Does your customized suspend script do
sync && sync && sync
sleep 3
zzz
to make sure all outstanding disk I/O is complete before you
actually suspend?
5. Are you running any detachable devices (PCCard or USB) when you
suspend? If so, you may want to detach them in rc.suspend and
re-attach them in rc.resume.
You said you've already created a hibernation slice. If you've done all
these things, and if your X31 works at all like my T23, suspend and
hibernate should work well, except for the need to switch to a virtual
console and back to X when you wake up from hibernation.
