Console output during boot goes silent

I'm watching the current MachineKit boot, and it goes silent after a time:

debug: [console=ttyO0,115200n8 bone_capemgr.uboot_capemgr_enabled=1 root=/dev/mmcblk1p1 ro rootfstype=ext4 rootwait coherent_pool=1M net.ifnames=0 quiet] ...
debug: [bootz 0x82000000 0x88080000:44345f 88000000] ...
## Flattened Device Tree blob at 88000000

Starting kernel ...

[ 0.001888] timer_probe: no matching timers found

[ 2.012033] omap_voltage_late_init: Voltage driver support not added

At that point, there's no more logging for a long time, until it finally prints

rootfs: clean, 67056/238560 files, 436721/953344 blocks

then a shorter delay (5-10 seconds), and then it finally prints the login prompt.

Is there a way to see the entire boot sequence?



and remove "quiet"..
