Public bug reported:
Hi,
after updating to Ubuntu Desktop 7.04 from 6.10, starting the ACPI
services during boot causes a segmentation fault on a Fujitsu-Siemens
Primergy Econel 50. Booting the machine with acpi=off works fine.
On the boot screen, this looks like
...
* Starting ACPI Services [Ok]
Segmentation fault
* Starting system log daemon [Ok]
...
* Starting Hardware abstraction layer hald _
After that, the machine hangs for a couple of minutes, then the screen
goes blank.
Here is an excerpt from /var/log/syslog:
