Hum, interesting, I am not reproducing the exact same problem (but I
was testing on ARM, with a slightly different defconfig). I believed
I've fixed the problem I was seeing. I've now started a build with your
defconfig, to see if I reproduce the same problem.
So, it's under investigation.
Best regards,
Thomas
