Subject: Cannot make a disk image for the BeagleBone Black
Date: Fri, 20 Sep 2019 16:52:41 -0400

[Message part 1 (text/plain, inline)]

Hi Guix,

I’ve been trying to build a disk image for the BeagleBone Black.  After
fixing <https://bugs.gnu.org/37384>, I’m now hitting a problem when Guix
manipulates the image from QEMU.  One of the Linux kernel modules seems
to crash.  For the record, I’m building the image from an armhf machine.
I’ve attached the error.

… or is it that shepherd could not be spawned for some reason?

Could it be that our kernel config for ARMv7 is wrong somehow?

I assumed so.  Is this the output you would expect if the unhandled
fault stuff was just a warning which was followed by Shepherd failing?

Is it the “init Not tainted” part that makes it look like Shepherd is
having problems?

> Could it be that our kernel config for ARMv7 is wrong somehow?

I was guessing that it was a problem with the modules (either that we
are missing something in the kernel config or we are not including
something in the initrd).  However, I guess it could also be a change in
how we invoke QEMU.  I haven’t had a chance to dive into it yet, I was
hoping that someone “out there” might know something!  :)

I was able to build an image for the Beaglebone Black, and it even
booted!  It seems whatever problem I had has disappeared.  Closing.
