yes, thanks, the panic has gone away.
There still seems to be a problem with this device:


hdac0_at_pci0:0:20:2:	class=0x040300 card=0x30c2103c chip=0x43831002 rev=0x00 hdr=0x00
    vendor     = 'ATI Technologies Inc. / Advanced Micro Devices, Inc.'
    device     = 'IXP SB600 High Definition Audio Controller'
    class      = multimedia
    subclass   = HDA


hdac0: <ATI SB600 High Definition Audio Controller> irq 16 at device 20.2 on pci0
hdac0: HDA Driver Revision: 20100226_0142
hdac0: [ITHREAD]
hdac0: hdac_get_capabilities: Invalid rirb size (0)
device_attach: hdac0 attach returned 6


I understand from the manual, there should 
be devices /dev/pcmX and /dev/dsp, but I have neither.

I'll ask in _at_questions.

many thanks for a quick fix!
