Did "apport-collect" but with wrong kernel - I'm just testing 2.6.30 :/
I'll do it later again with 2.6.28 kernel.
I just tested mainline kernels:
* 2.6.29-02062904-generic
* 2.6.30-020630-generic
both kernels work well with "acpi=off".
If I remove "acpi=off" kernel 2.6.29 behaves same as 2.6.28 (delivered with ubuntu 9.04) - systems hangs at "loading, please wait..."
Kernel 2.6.30 without "acpi=off" did little bit more - ubuntu boot-screen came but then system hangs. IO-problems with harddisk. See (real) screenshot in the attachement.
