Hi Khem,

Thanks for the upgrade. I can see two failures here: I believe the first
one is expected, but not the second one.

So first, buildtools builder is failing with:
ERROR: Failed to spawn fakeroot worker to run /srv/pokybuild/yocto-worker/buildtools/build/layers/openembedded-core/meta/recipes-kernel/linux-libc-headers/linux-libc-headers_6.18.bb:do_install: [Errno 32] Broken pipe

https://autobuilder.yoctoproject.org/valkyrie/#/builders/43/builds/4256
I believe this is just because we need to rebuild uninative on glibc
upgrade.


The second issue is a ptest failure:
Failed ptests:
{'m4': 'START: ptest-runner\n'
...
       'EAGAIN == EWOULDBLOCK == 11\n'
       'ENOTSUP == EOPNOTSUPP == 95\n'
       'PASS: test-errno-h\n'
       'PASS: test-error.sh\n'
       'test-execute-main: test-execute-child subprocess failed: No such file '
       'or directory\n'
       'Timeout! System state:\n'
       'Collected system state:\n'
       '+ dmesg\n'
...
       'ERROR: Exited from signal Killed (9)\n'
       'DURATION: 451\n'}

Can you have a look at that last issue?

Thanks,
Mathieu
