Public bug reported:

Binary package hint: pm-utils

Hi,
AFter upgrading to Hardy, suspend worked but resume consistently failed: the 
laptop froze straight after resuming, without the smallest disk activity, no 
LCD backlight, no blinking cursor. The magic-key combination (Alt-SysReq) didnt 
work either. Not even power cycling could get the laptop to boot again. The 
only way was to disconnect the power cord and remove the battery. Only then 
would the machine boot again.
I tried the debugging suspend procedure (from 
https://wiki.ubuntu.com/DebuggingKernelSuspend) and found out that using "sudo 
/etc/acpi/sleep.sh force" resume worked fine. 
I m happy to help find out why pm-suspend doesnt work when sleep.sh does for me.
Meanwhile, to fix things on my laptop, I edited 
"/usr/lib/hal/scripts/linux/hal-system-power-suspend-linux" and replaced the 
"if [ -x "/usr/sbin/pm-suspend" ]" statement around lines 72 with 
"/etc/acpi/sleep.sh; RET=0" and suspend/resume both work fine now.
I have attached the output of lspci-vv and can provide more if required.
