[Bug 29695] Re: after sleep+resume I can't restart the system

[John Cranney]

I've been playing with this all day. I started off with a clean dapper
install.  "out of the box" the laptop suspends OK. However on resume
screen is blank, consoles are not available, and machine does not
respond to pings.

I have tried the following:

Added vga=normal to kernel args (no change)
Removed splash from kernel args (no change)
In /etc/default/acpi-support, changed acpi_sleep=mem to acpi_sleep=stanbdy (machine does not suspend)
In /etc/default/acpi-support, commented out POST_VIDEO=true (no change)
In /etc/default/acpi-support, uncommented ACPI_SLEEP=TRUE (no change)
In /etc/default/acpi-support, uncommented save_video_pcistate (no change)
In /etc/default/acpi-support, commented oiut USE_DPMS=true (no change)
In /etc/default/acpi-support, uncommented disable_dms=true (no change)
In /etc/default/acpi-support, uncommented reset_drive=true (no change)
Added reboot=h to kernel args (no change)
Added noapic to kernel args (no change)
Added noalpic to kernel args (no change)
Added acpi_sleep=s3_mode to kernel args (no change)
Added acpi_sleep=s3_bios to kernel args. This definitely changes something- I get "inu" in yellow in the top left of the screen, then I get some messages saying "hbd: drive not ready for command". Console are available but do not respond to enter key. Occasionally when I resume using this option the desktop comes back OK, but it normally freezes after the second suspend.

Can I get some help with this please? I'm kinda just trying stuff
without really understanding what I'm doing :) Can anyone suggest other
things to try?

I have output of 
sudo dmidecode > dmi.txt
dmesg >dmesg.txt
lspci -vn > lspcivn.txt
lspci -vvn > lspcivvn.txt

if anyone wants to take a look- just email me.  I know this laptop will
suspend OK because I had it working under slackware.

Help please!
