Grub2 countdown slow


Answer: 1

14 hours ago

When booting I have a 3 seconds grub timeout and a countdown to show it:


problem is that the 3 seconds countdown countdown takes over 1 minute ! Even worst, I have a feeling it is slowly getting worst :-( (or may be I am becoming more and more impatient)

version is: grub-common_2.02~beta2-36ubuntu3.12_amd64.deb Ubuntu xenial installed on a Macbook

Found a few posts reporting the same problem on the net, but no solution :-(

Anybody has an idea what could be the problem (and the solution)?

For the record, the following post describes (more accurately) the same problem I had. It also proposes a solution (post #6): "1. Boot the Apple computer to grub, takes about 2 minutes 2. Press a key, then edit your boot configuration to include the kernel command line parameter break, takes about 2 minutes 3. At the initramfs prompt usb works fine. Enter command reboot 4. This initiates a graceful shutdown of Linux, and the Apple computer can now be booted with usb3 operating normally"

Another post (#28) also proposes: "I updated to kernel 4.12 and the kernel recover usb failures on boot"

None of these worked for me :-(
