Thanks for reporting this. I don't know quite how to proceed from here; the modified
kernel boots for me just fine. The code we modified shouldn't even be called this
early -- it's around file descriptor handling, and I don't think we even get a
file descriptor this early in boot.
Can you share the ramdisk that you're booting the kernel with?

Thanks for reporting this. I don't know quite how to proceed from

descriptor handling, and I don't think we even get a file descriptor
this early in boot.
Can you share the ramdisk that you're booting the kernel with?
Have you tried the attached reproduce-* script in the original email?
It works for me. That script does not include the ramdisk download
part because initrd is not necessary/relevant for reproducing this
bug. In fact all ramdisks we tested can trigger it.
Thanks,
Fengguang

Oops, that's our internal merge commit, so it's reasonable you cannot
reproduce the bug on your tree. Sorry for the noise!
