Hi,

i'm trying to install Dragonfly-BSD (dfly-1.6.0_REL.iso) with GENERIC kernel on 
my laptop (details at the end of this email). But everytime i boot from the 
installation media i get a kernel panic like this (in verbose mode):
---------------
cbb1: <TI1225 PCI-Cardbus Bridge> at device 10.1 on pci0
cardbus1.cbb1.pci0.pcib0.legacypci0.nexus.0.root0
cardbus1: <CardBus bus> [tentatitive] on cbb1
cardbus1: <CardBus bus> [attached!] on cbb1
pccard1.cbb1.pci0.pcib0.legacypci0.nexus0.root0
pccard1: <16-bit PCCard bus> [tentative] on cbb1
pccard1: <16-bit PCCard bus> [attached!] on cbb1
pci_cfgintr_unique: hard-routed to irq 10

could you enter "trace" at the debugger prompt and paste the output (if you have to transcribe it manually, the function names should be enough for the beginning)?

cheers
