Good news --- jump from 2.6.13-rc3 to 2.6.16 (almost) ok (swsusp, input)

[Romano Giannetti]

Hi all. 

I finally tried to install 2.6.16 on my portable PC, jumping directly from
2.6.13-rc3, and there are good news. The most critical thing, namely swsusp,
did work ok and seems faster than before. A little problem is that when
starting the suspend, no messages are printed (the screen goes blank and
after a bit the machine poweroff). But then resume is ok . The same goes for
-ck1,  which has a really nice feeling.

The only little problem is with the synaptics ALPS touchpad. It seems that the
"event" interface changes at every reboot, and the method "use device
/dev/psaux" and protocol "auto-dev" does not work. All logs are here:

Thanks for the good work, all.

PS: this is probably offtopic, but my laptop started doing a very strange 
thing. When powered off and then rapidly powered on, it stays stuck at the
"Sony" logo page. I have to wait 2 to 3 minutes to have it enters LILO. Any
idea? I lost time too; could the little bios-backup battery be responsible? 
Thanks!

See FAQ:

Q: How do I make suspend more verbose?

A: If you want to see any non-error kernel messages on the virtual
terminal the kernel switches to during suspend, you have to set the
kernel console loglevel to at least 4 (KERN_WARNING), for example by
doing

        # save the old loglevel
        read LOGLEVEL DUMMY < /proc/sys/kernel/printk
        # set the loglevel so we see the progress bar.
        # if the level is higher than needed, we leave it alone.
        if [ $LOGLEVEL -lt 5 ]; then
                echo 5 > /proc/sys/kernel/printk
                fi

        IMG_SZ=0
        read IMG_SZ < /sys/power/image_size
        echo -n disk > /sys/power/state
        RET=$?
        #
        # the logic here is:
        # if image_size > 0 (without kernel support, IMG_SZ will be
zero),
        # then try again with image_size set to zero.
        if [ $IMG_SZ -ne 0 ]; then # try again with minimal image size
                echo 0 > /sys/power/image_size
                echo -n disk > /sys/power/state
                RET=$?
        fi

        # restore previous loglevel
        echo $LOGLEVEL > /proc/sys/kernel/printk
        exit $RET
