Thought I had the same thing here, AMD, upgrade from dapper. Slow boot from grub, I see the usplash initially, but then it goes to blinking cursor, hard drive light *blinks* furiously. Tried a 'noquiet' 'nosplash' suggested above, but it does the same thing (HD starts blinking, screen sits for at least 3 minutes) when loading my USB drivers). This happens even without my mouse plugged in. After more searching, I found bug #68888 and bug #67299 which seemed to have similar symptoms. Oddly enough, the upgrade created an ARRAY entry in my /etc/mdadm/mdadm.conf even though I don't use any software RAID. After much trial and tribulation, this got my system back on track:
1) remove the ARRAY entry in /etc/mdadm/mdadm.conf 2) run 'sudo dpkg-reconfigure mdadm, answer the questions, defaulting to no since I don't use software RAID. This will update the initramfs for the kernel 3) reboot Now my boot time is back to normal! -- no boot splash and very slow booting https://launchpad.net/bugs/61711 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
