Comment 0 for bug 1055506

After upgrading (with do-release-upgrade) the OS to Ubuntu 12.04.1 LTS, the system failed to boot. It failed to find any disks. Boot process ended with the "(initramfs)" prompt. Output attached. Found workaround by adding "acpi=off" to boot options.

Falling back to old kernel (2.6.32-43-server) the system booted fine.

Tried the following option with the new kernel (3.2.0-31-generic):

noapic -- failed
nolapic -- failed
acpi=off -- worked
acpi=ht -- failed
