Output log on a serial console
I tried to boot 11.2-RC1 RPI2 image with RPI2 B V1.2 and it hangs during boot.
BETA3 image does not have this problem.

Output log from RPI2 B V1.1
I tried the same 11.2-RC1 image with RPI2 B **V1.1**, too.
This time it booted up without a problem.
I tried the RC3 image with an RPI2 B 1.2.
It still hangs at the same location, just after printing the line:
cryptosoft0: <software crypto>

Output log with debug-enabled kernel
I replaced kernel files in the RC3 image with those with debug functions enabled.
The following options were added to RPI2 kernel config:
# For full debugger support use (turn off in stable branch):
options DDB # Support DDB
options DEADLKRES # Enable the deadlock resolver
options INVARIANTS # Enable calls of extra sanity checking
options INVARIANT_SUPPORT # Extra sanity checks of internal structures, required by INVARIANTS
options WITNESS # Enable checks to detect deadlocks and cycles
options WITNESS_SKIPSPIN # Don't run witness on spinlocks for speed
options MALLOC_DEBUG_MAXZONES=8 # Separate malloc(9) zones
options ALT_BREAK_TO_DEBUGGER # Enter debugger on keyboard escape sequence
options USB_DEBUG # Enable usb debug support code
# Optional extras, never enabled by default:
options DEBUG # May result in extreme spewage
options VERBOSE_SYSINIT # Enable verbose sysinit messages
The output from the debugging kernel is attached.
