Comment # 5 on bug 935086 from Uwe Geuder

Thanks for the quick reply!

- No remote filesystem whatsoever.
- Ethernet
- NetworkManager
- nothing non-default comes to my mind (the boot subvolume on the btrfs rootfs
created by the installer has been deleted after installation. But I guess
that's more like a bug/misfeature in the installer that it creates such
subvolume when a separate /boot filesystem is in use)

Why did you you ask for network? It is my understanding (without deeper
analysis) that the network comes up  first in the real root filesystem, but the
hang occurs while still in initramfs. At least what I have observed. Of course
if rootfs were on a a network filesystem the network would be required already
in initramfs. So there some logic that brings the network up conditionally in
initramfs? At least it should not be needed in my setup and the problem is the
same whether the netwrok cable is attached or detached at the time of resuming.
