[ltp] swsusp / t23

[Christopher Hubbell]

Greetings,

I think I'm very close to conquering suspend to disk on my T23, but I've 
hit a wall and am hoping someone else has broken through.  Here's my 
environment:

Kernel:  2.6.9.rc1
ibm-acpi: v0.3
Dist: Fedora Core 2

Grub.Conf:
  kernel /vmlinuz-2.6.9.rc1-cgh2 ro root=LABEL=/ rhgb quiet 
resume2=/dev/hda6

/etc/acpi/events/f12.conf:
  event=ibm/hotkey HKEY 00000080 0000100c
  action=/etc/acpi/actions/suspend2disk.sh

/etc/acpi/actions/suspend2disk.sh:
  #!/bin/bash
  rmmod uhci_hcd
  echo "disk" > /sys/power/state
  modprobe uhci_hcd

I know that the acpi event is being properly trapped from the acpid log:

[Wed Oct 13 05:20:05 2004] received event "ibm/hotkey HKEY 00000080 
0000100c"
[Wed Oct 13 05:20:05 2004] notifying client 2472[500:500]
[Wed Oct 13 05:20:05 2004] executing action 
"/etc/acpi/actions/suspend2disk.sh"
[Wed Oct 13 05:20:05 2004] BEGIN HANDLER MESSAGES
[Wed Oct 13 05:20:22 2004] END HANDLER MESSAGES

[Wed Oct 13 05:20:22 2004] completed event "ibm/hotkey HKEY 00000080 
0000100c"

And I see the display change to text mode, and go through the normal 
messages

So, it looks like eveything works, but it never actually suspends...  It 
just suspends, then goes right back to the graphical display...  I'm 
suspicious of the floppy0 error, but I have no idea where this would be 
coming from since I don't have a floppy drive.  I don't even have the 
floppy module loaded:

I'm sure this is something obvious I'm overlooking - any RTFMs or help 
would be greatly appreciated!

Thanks,
Chris
