Hello,
After upgrading from Ubuntu 6.10 to 7.04 Suspend to RAM does not
function. After two days of minor tweaking of Ubuntu, Ubuntu 7.04
reports "Internal error: failed to initialze HAL!". The buttons Gnome
main menu System > Quit > 'Suspend to RAM' and 'Suspend to Disk' 
disappear now and then. Their equivalents in the context menu of the
Gnome Power Manager remain, though.
0. Kernel version: Linux Amilo7600 2.6.20-16-386 #2 Thu Jun 7 20:16:13
UTC 2007 i686 GNU/Linux.
1. It appears in the latest kernel version of my avail.
2. This problem did not exist in its entirety in earlier Linux kernel
versions I have tried.
3. It is no regression.
4. I attach dmesg -s64000.
5. I attach lspci -vv.
6. I attach acpidump.
7. I attach dmidecode.

How to get rid of the error message "failed to initialze HAL!"? How to
resume normally from Suspend-to-RAM and Suspend-to-Disk?

Regards,
Detlef Lechner
