what do you use for hibernate? is that hibernate to RAM (with
the battery trickle feeding memory so that memory doesn't go away)
or is that suspend to swap?
im using acpi_sleep.
i use suspend to swap, so my kernel cmdline has:
resume=/dev/hda3
and then i have a suspend script that does the ff:
== start of script
#!/bin/bash
# mysql just won't susp nicely.
service mysqld stop;
echo shutdown > /sys/power/disk; echo disk > /sys/power/state
service network stop;
service network start;
dhclient eth0;
ifconfig vmnet8 192.168.2.1
ifconfig lo 127.0.0.1
server mysqld start;
== end of script
you need software suspend built into your kernel, of course.
i don't know what the recommended size of swap is, mine is around
200MB larger than my RAM. works great, although mandriva's
kernel 2.6.12-15 (with tweaks) starts slower than the previous
version (i forget what it was). still faster than booting from
scratch though, and since i mostly use it on long trips, when
I use cpufreq to slow down the CPU (to save battery) and because
i can safely swap batteries (i don't think hibernate to RAM works
that way), it works great.

software suspend is already enable in my kernel, i think there is
problem with the configuration.
can anyone help.
thanks
