[Bug 1237733] Re: Kernel hangs on wandboard (freescale imx6)

 

where does the dtb reside in this case? mmc or flash?

in any case, try updating it with the last one that you can find in
/lib/firmware/$kernel-version/device-tree/imx6q-sabrelite.dtb

Title:
  Kernel hangs on wandboard (freescale imx6)

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I've been trying to use the generic kernel with my wandboard (based on
  a freescale imx6) as it's supposed to be working properly.

  Using the Ubuntu generic kernel, I usually get a successful boot very shortly followed by a hang.
  The hang is: http://paste.ubuntu.com/6216221
  That's when using: vmlinuz-3.11.0-12-generic
  dmesg for that kernel: http://paste.ubuntu.com/6216265/

  
  Then I noticed that fedora's 3.11 kernel appears to work fine for me and is reasonably stable (though it lacks aufs and overlayfs which I kind of need since I use the board as a buildd).
  The fedora kernel I'm using is: vmlinuz-3.11.0-armv7-x13
  dmesg for that kernel: http://paste.ubuntu.com/6216246/

  A config diff between the two gives me:
  http://paste.ubuntu.com/6216233/

  I believe the git branch for the fedora kernel is at:
  http://pkgs.fedoraproject.org/cgit/kernel.git
