Bug Description
I downloaded and tried to load the 20090319 daily live CD image of the 32-bit version of Jaunty Jackalope.
While booting up on one of my desktop computers with a ECS GeForce 6100PM-M2 motherboard, after the language window disappears a black screen appears with one line of text at the top that states:
[1.####] ACPI: expecting a [Reference] package element, found type 0
and then the computer immediately shuts off.
I tried the same live CD image in my Toshiba A105-S2091 laptop computer and Jaunty Jackalope booted up.
There was a black screen that appeared briefly with one line of text at the top in the same sequence as desktop computer that states:
[####] ACPI: DMI BIOS year ==0, assuming ACPI-compatible machine
but the screen disappeared after a few seconds and Jaunty Jackalope continued booting normally.
I later downloaded and tried to load the 20090319 daily live CD image of the 64-bit version of Jaunty Jackalope on the desktop computer (the laptop is not 64-bit compatible).
The 64-bit version experienced the identical problem as the 32-bit version with error message and shutdown on the desktop computer.
This problem did not occur when I tried a daily live CD image of Jaunty Jackalope last week, so this got messed up in the last few days.
Update: I downloaded and tried to load the 20090320 daily live CD image of the 32-bit version of Jaunty Jackalope.
The problem on one of my desktop computers with a ECS GeForce 6100PM-M2 motherboard had not been resolved.
I tried the same 20090320 daily live CD image of the 32-bit version of Jaunty Jackalope on my desktop computer with an ECS 945GCT-M/1333 motherboard, and the ACPI error messages and system shutdown did not occur.
Update: I downloaded the beta release of Ubuntu 9.04 and it still has the identical problem.
It would help if this problem got fixed at least enough to prevent the live CD of Ubuntu 9.04 from powering down my computer with the ECS GeForce 6100PM-M2 motherboard before it can boot up completely.
Update, April 5: I downloaded the 20090403 daily build of Ubuntu 9.04 (x86 version) and it still has the identical problem.
It would be very annoying if this bug survives final release.

Update, April 22: I downloaded the release candidate image of Ubuntu 9.04 (x86 version) and it still has the identical problem.
I have the latest BIOS installed on the ECS GeForce 6100PM-M2 motherboard.
Since this bug causes a computer with the ECS GeForce 6100PM-M2 motherboard to shut down before it can boot up completely with the live CD/DVD, I consider this to be a critical bug for computers using an ECS GeForce 6100PM-M2 motherboard.
