hi,
in current git my booting takes > 20 s longer.
I bisected this to "net: restore the original spinlock to protect unicast list" commit: a6ac65db2329e7685299666f5f7b6093c7b0f3a0
reverting this commit gives me back 20 s in boot time.
I've attached the two dmesg logs.
I can help with testing if necessary.
Regards,
Henk

Try adding this patch from Ingo. It will probably fix the issue:
