qemuppc is randomly hanging at boot during sanity testing. For example:
- https://autobuilder.yocto.io/builders/nightly-ppc-lsb/builds/581
- https://autobuilder.yocto.io/builders/nightly-ppc/builds/592
Despite initial suspicions this was not due to entropy problems.
It is *not*:
- Specific to a host OS (observed on centos7, debian8, ubuntu1710)
- Specific to image recipe (happens sato, sato-sdk, lsb, lsb-sdk)
- Specific to DISTRO (poky and poky-lsb)
The hang usually occurs after:
[ 6.667445] udevd[104]: starting version 3.2.2 [ 6.743262] udevd[105]: starting eudev-3.2.2
and is hanging in the poll() call in udevadm-settle.c:adm_settle(), it doesn't seem to return from the syscall.
In some cases the boot proceeds further and hangs in the dropbear key creation.
