Flashing cursor when rebooting / Blackscreen

    • Seems like I found the solution - but I am not sure yet. Will look if the reboots are consistent and stable, because my first OMV-installation rebooted sometimes fine and then suddenly it wouldn't work anymore for some reasons.

      I was asking for help in a few #debian IRC channels and somebody immediately suggested to try different "reboot="-kernel options.

      reboot= [KNL]
      Format (x86 or x86_64):
      [w[arm] | c[old] | h[ard] | s[oft] | g[pio]] \
      [[,]s[mp]#### \
      [[,]b[ios] | a[cpi] | k[bd] | t[riple] | e[fi] | p[ci]] \
      [[,]f[orce]
      Where reboot_mode is one of warm (soft) or cold (hard) or gpio,
      reboot_type is one of bios, acpi, kbd, triple, efi, or pci,
      reboot_force is either force or not specified,
      reboot_cpu is s[mp]#### with #### being the processor
      to be used for rebooting.


      At first none of them did work (not even reboot=efi). Wen't to the UEFI and enabled Legacy-Mode again (Linux has no problems with switching UEFI/Legacy-mode on the fly it seems) and it booted up fine.
      Opened up a terminal per SSH, logged in as root and:
      nano /etc/default/grub
      changed GRUB_CMDLINE_LINUX="" to GRUB_CMDLINE_LINUX="reboot=bios"

      Saved everything, ran "update-grub" and rebooted without any issues so far. Hopefully it will stay like that :)

      Just because of the screen, I could live without it. But if you need to use it then i guess you need to fix that. I noticed that you cloned the other install from the SSD, i would try clean install also.


      Oh my. NOW I know what you mean. I would not care at all if it only was a graphical output problem. That was NEVER the case. The whole system would not even boot, it was a complete freeze. Sometimes at shutdown(okay, that only happened when I experimented with different reboot=-kernelparameters), always at/after GRUB (but only when I rebooted). Was I not specific enough? Tried my best to deliver all informations that I could give :/

    • Did you try GRUB_CMDLINE_LINUX="reboot=acpi".
      This works for me until 3 Days with at least 10 reboots via GUI.
      I'am using the standart OMV install without any kernel-backport etc.
      only Samba,NFS, autoshutdown-plugin....

    • I can confirm I have such problems very rarely, too. If i reboot manually by pressing the reboot button, it boots up just fine. Hard sometimes if I wake it up remotely via WOL and hope it´ll start properly. Don´t know when it happened first, a few months ago. But it happened about 3 times since then. Did not try anythin till now.

      Yep, I've tried that one also - Was not consistent enough. The problem came back after a few days.

    • Hi,
      I have same problem, sometimes (very often) when I restart system from the Start menu, booting stuck with black screen and blinking cursor in the top left corner. I tried update BIOS and different options in BIOS and no change,,,
      My configuration:
      - ASRock Q1900-ITX
      - OS Windows Server 2012
      - 2x2GB RAM Transcend 1333MHz, TS256MSK64V3N
      - HDD 2TB WDC WD20EARS with OS + HDD 3TB WDC WD30EZRX
      - picoPSU power supply

      Did you resolve this issue ?
    • I fixed mine with changing my Boot priority. Sometimes I had a USB drive connected to OMV. It somehow wanted to boot from that stick and it ended in a flashing cursor...

    • No external devices are attached at my server - also rebooting with ubuntu and windows works without any trouble.
