This appeared in -bk-latest in the past day or two.
BK-current on x86-64 (config/dmesg/lspci attached) will pause for 30
wall-clock seconds immediately after being loaded by the bootloader,
then will proceed to boot successfully and function correctly. This
is reproducible on every boot.
So, 30 seconds with no printk output, then boots normally.
Boot with earlyprintk=serial,ttySx,baud or earlyprintk=vga
That should enable printk from the beginning and may give
some clues.
