Kernel stuck on boot after sio0 probe

Hi there,

a new kernel from about three hours ago is stuck at boot after the sio0
probe:

sio0: configured irq 4 not in bitmap of probed irqs 0
sio0: port may not be enabled
sio0 port 0x3f8-0x3ff irq 4 on acpi0
sio0: type 8250 or not responding

Then nothing, not even on verbose boot.

Usually it would continue with the ppc0 probing stuff:

ppc0 port 0x3bc-0x3c3 irq 7 on acpi0
ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode
ppbus0: <Parallel port bus> on ppc0
ppi0: <Parallel I/O> on ppbus0

Last known working kernel is from Fri May 28 11:49:33 CEST.

Any ideas?

cheers,
le
