Long boot time on new install

1st Official Post

    Hi,

    I have a small problem wih slow booting :)

    Fresh install via USB creator on new HDD in my HTPC, Libreelec now boots over 2 minutes.

    On previous older HDD it was much faster to boot.

    Any ideas how to debug this?

    Code
      LibreELEC:~ # systemd-analyze
Startup finished in 2min 25.998s (kernel) + 49.524s (userspace) = 3min 15.523s

    According to dmesg timestamp, these is 2 minutes pause before mounting ext4 filesystem, here is the relevant part:

    I don't see anything wrong with the drive, passed all smartctl tests, here is hdparm quick bench:

    Code
    LibreELEC:~ # hdparm -Tt /dev/sda

/dev/sda:
 Timing cached reads:   1306 MB in  2.00 seconds = 652.23 MB/sec
 Timing buffered disk reads: 386 MB in  3.00 seconds = 128.48 MB/sec

    I've got no idea what the issue is or how to debug SATA initialisation problems, but I'll pass the observation that you're running tests on the drive *after* it is has completed initialisation, and it looks like the initialisation process is where the delay is incurred.

    Can you connect the drive to an alternative SATA port? .. any firmware/BIOS updates available for the HTPC?

    Thanks for the quick response.

    I'll try swapping the cables and ports. It's an older AMD APU based HTPC with the failing HDD, no BIOS updates. I don't know if it is SATA problem, there are no errors in dmesg. no lowering SATA link speeds, it just waits for Godot for 2 mins :)

    This HDD is advanced fromat (4kB blocks), maybe the kernel is having trouble with it. Too bad it doesn't output anything in that interval at 8-143s mark. Looks like I have a lot of googleing to do :)
