had the same problem. it seemed an acpi problem at first, but it turned out it was related to my hard drive not being properly detected. if you remove "quiet splash" from the kernel boot options (in grub) you will see that the last kernel message is "Waiting for root filesystem..." instead of "getting cpuindex of acpiid".
anyway, the way i fixed it was rebuilding the initramfs. in ubuntu you can do that by issuing this command: update-initramfs -k 2.6.17-10-generic -c or replace 2.6.17-10-generic with the kernel version you want to generate the initramfs for. -- getting cpuindex for acpiid 0xnn delay on booting Edgy https://launchpad.net/bugs/62608 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
