I've tested and it worked for me. I'm able to suspend my Acer Travelmate 8471, Bios 1.27, Ubuntu Lucid Lynx 10.04 with 2.6.32-16-generic.
So we need confirmation which other variations works with this patch.
For testing you can hold down [Shift] while grub is loading during boot process.
Add this boot param in the kernel line (beware of the line break):
i8042.reset=1
If it works you can make changes persistent in Lucid Lynx with editing /etc/default/grub with root rights and add the boot param to this line so it looks like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.reset=1"
Stefan:
Thanks for your dmesg, I wasn't able to get an useful output after:
sh -c "sync; echo 1 > /sys/power/ pm_trace; pm-suspend"
but you did it!
Latest hash matches in your dmesg was:
[ 0.781706] i8042 aux 00:08: hash matches
So i've googled around and found these bug report: /bugs.launchpad .net/ubuntu/ +bug/236656
