Any progress here?

I see you have a thinkpad, so with right console loglevel, you should
be able to see the messages just after boot...? Where does it really
hang

[ 0.955389] Back to C!
[ 0.389803] PM: Writing back config
space on device 0000:00:01.0 at = offset
1 (was 100107, writing 100507)
[ 0.389814] PCI: Setting latency
timer of device 0000:00:01.0 to 64

Is it here?

[ 120.599158] PM: Writing back config
space on device 0000:00:1b.0 at = offset
1 (was 100006, writing 100002)
[ 120.599185] ACPI: PCI Interrupt
0000:00:1b.0[A] -> GSI 16 (level, lo= w)
