[Kernel-packages] [Bug 1950792] Re: No boot possible - Cannot open root device

[Jerzy Husakowski]

We suspect that on the affected systems the length of the kernel options
cmdline exceeds the allowed maximum. Would it be possible to share the
kernel options MAAS sends for machines that fail to deploy this way? The
kernel options could be retrieved using IPMI console.

Title:
  No boot possible - Cannot open root device

Status in MAAS:
  Incomplete
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  MaaS cannot boot on my X11DPi-NT and will therefore fail to
  commission. It will instantly fail after grub.

  It will fail to boot saying that is not able to open root device. I
  even tried supplying the squashfs via python on a different port as
  the url is somehow cut off a bit, but to no avail. The python
  webserver doesn't even see any connection try.

  ( custom kernel params: root=squash:http://10.0.33.253:8080/squashfs
  python webserver: python3 -m http.server 8080)

  Steps to reproduce:

  1. Setup maas ;)
  2. Try to commision server
  3. See the kernel and initrd download fly by 
  4. Boom kernel panic

  Hardware:
  Supermicro X11DPi-NT with UEFI http Networkboot enabled
  NIC: Intel X722

Title:
  Mouse pointer disappears on the second screen [Failed to post KMS
  update: drmModeAtomicCommit: Device or resource busy]

Status in linux package in Ubuntu:
  Incomplete
Status in mutter package in Ubuntu:
  New

Bug description:
  On a setup with two screens (primary: laptop screen, secondary:
  external monitor via thunderbolt & docking station), when moving the
  mouse from the primary to the secondary screen, the mouse pointer
  becomes invisible. Waving the mouse and clicking on windows sometimes
  helps.

  Journalctl shows "Failed to post KMS update: drmModeAtomicCommit:
  Device or resource busy" from gnome-shell, which is perfectly timed
  with when I move the mouse pointer to the secondary screen. There's a
  kernel stack trace immediately before that message
  (drm_atomic_nonblocking_commit).

  The issue started occurring 1-2 weeks ago, I suspect immediately after
  installing system updates.
