Meanwhile I found out what's the cause of it. On 9.x it only hung from time to time, but I tried a few weeks old CURRENT and it hung at every boot at the same time. With enabled verbose boot it looked like this: http://bsd-geek.de/FreeBSD/IMAG0190.jpg Then I removed the AC cable and booted from battery and that worked. So it seems to me that some ACPI change in CURRENT made the situation even worse.
