I have a similar box to yours:

[ 0.382127] smpboot: CPU0: AMD PRO A12-8800B R7, 12 Compute Cores 4C+8G (family: 0x15, model: 0x60, stepping: 0x1)

...

[ 0.974044] x86/pm: family 0x15 cpu detected, MSR saving is needed during suspending.

well, Bulldozer-based at least, and booting with kmemleak enabled is fine:

$ cat /sys/kernel/debug/kmemleak
$

I wonder whether you have something else applied and forgotten along
with all those random printks I'm seeing in dmesg...

Also,

unreferenced object 0xffff8914823de500 (size 64):
^^^^^^^^

That's strange too - sizeof(struct saved_msr) is 40 and not 64 so that
looks weird...
