Ticket #8194 (closed defect: duplicate)
Vbox 4.02, Ubuntu 10.10 x64 guest live install hangs (on Windows 7 x64 host), requires acpi=off to fix
|Reported by:||heckheck||Owned by:|
When attempting to install an Ubuntu 10.10 x64 guest on a Windows 7 x64 host using VBox 4.02, the Ubuntu installer consistently hangs as the kernel gets to line
Freeing initrd memory: 11516K freed
Adding the kernel boot option acpi=off (using f6 of the Ubuntu live CD installer) gets past this hang.
I had just upgraded this machine to VBox 4.02 from VBox 3.2.12, and just prior had NOT experienced this hang when installing using the same Ubuntu 10.10 x64 image on 3.2.12, so it may be a regression.
I also tried Ubuntu 10.04 x64 install media with VBox 4.02 and ran into the same problem.
I tried two version of 32bit Ubuntu 10.10 with VBox 4.02 (10.10 and a 10.04beta) and did not experience the problem (it only happens with the x64 versions).
I have not installed the 10.10 x64 fully, so I do not know if I will need the acpi=off kernel parameter once the OS is installed.
VBox.log attached for failing and passing (with acpi=off) case
