I tested with fresh 10-CURRENT sources and got exactly the same result,
just two lines less in output. Last lines before hang are

pci0: <simple comms, UART> at device 14.0 (no driver attached)
puc0: <Oxford Semiconductor OX9160/OX16PCI954 UARTs (function 1)> port
0x1840-0x185f,0x1880-0x189f mem
0xe0080000-0xe0080fff,0xe00c0000-0xe00c0fff irq 11 at device 14.1 on
pci0

(this time on ALIX, but only device number differs)
