The weird thing is that:

1) You didn't see (like Andres):
Machine check in kernel mode.
 Caused by (from SRR1=149030): Transfer error ack signal
 Oops: Machine check, sig: 7 [#1]
But, OK, maybe machine check requires something additional in kernel,
I don't know...

2) You didn't see SSB messages
This is confusing. You should see SSB messages that appear before my
invalid read happens. Did you somehow disable most of the important
logs, or sth? Having ssb messages and the end of hung boot would
directly point you to ssb module.
