Suspend works with Feisty kernel, not Gutsy

[Bill Moseley]

This is on a Thinkpad T60p.

If I boot with 2.6.20-16-generic from Feisty suspend and hibernate
work fine.

But with the Gutsy kernel 2.6.22-14-generic the screen goes blank,
the little moon icon flashes, then nothing.  Just sits there.

If I run:

    sudo bash -xv /etc/acpi/sleep.sh 2> sleep.out

the last line of sleep.out is:

echo -n $ACPI_SLEEP_MODE >/sys/power/state
+ echo -n mem

but I'm not sure that's really the issue.

    $ cat /sys/power/state
    mem disk



Any ideas what I might try?  I'm not familiar with suspend, but it
looks like kernel suspend is compiled in (so I can't try building a
separate kernel module -- if there was one...)

$ fgrep SUSPEND /boot/config-2.6.2*
/boot/config-2.6.20-16-generic:# CONFIG_DISABLE_CONSOLE_SUSPEND is not set
/boot/config-2.6.20-16-generic:CONFIG_SOFTWARE_SUSPEND=y
/boot/config-2.6.20-16-generic:CONFIG_SUSPEND_SMP=y
/boot/config-2.6.20-16-generic:# CONFIG_APM_IGNORE_USER_SUSPEND is not set

/boot/config-2.6.22-14-generic:CONFIG_SUSPEND_SMP=y
