Hello People,

I compared the dmesg output from netbsd and linux and came to the
conclusion that my problem with the NEC EHCI is probably not the EHCI
driver itself, but the OHCI/ACPI one. In my laptop there are two OHCI
controllers for 5 Ports. Looking at the NetBSD output i saw that one of
them was unabled to be assigned to a interrupt. In response the EHCI
complains about a wrong number of companions.

Looking at the linux output I can see that the Interrupts (IRQ 10) are
assigned by the ACPI subsystem, but looking at the NetBSD dmesg i cannot
see that either ACPI or APM is running.

May be this sounds stupid, but is there a working ACPI implementation
for NetBSD? If so, how can I activate it a boottime?

thanks,

sebastian
