Apparently the filesystem you choose only affects the mount time, which happens after Grub's "Starting up" message. With reiserfs I saw a delay of 1 or 2 seconds, with ext2 and ext3 no noticeable delay.
The 30-40 seconds delay problem appears (at least in my case) BEFORE that message even appears, right after the first message: "Boot from (hd0,0) reiserfs ID etc...", as if Grub is probing the usb device. But why does this happen only to usb hdds? -- initrd image is read really slowly when booting from USB2.0 HDD https://bugs.launchpad.net/bugs/247960 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
