I'm still working on getting the BIOS logs to be emitted to file before
kernel startup (I can see them later on, but not right at boot).
Will double-check the actual affinity next time I reproduce it (testcase
has been going all day with no luck so far).
so the fix is Fam's 'aio: Do aio_notify_accept only during blocking
aio_poll'. I see you're running the qemu-kvm-ev from centos, if I read
the version tea-leaves right, then I think that patch is in the
2.10.0-21.el7_5.7.1 package I can see.
It looks like we do not have this fix in our code, will definitely be
giving it a try.
Thanks,
Chris
