    I'm running NetBSD -current on HP NX6110 laptop. It makes very fast 
and stable workstation, but there are some irritating glitches.
    - USB is not usable: Controllers are detected by kernel, they are 
shown in dmesg. However, connecting any USB devices does nothing. 
usbdevs output is weird too:

laptop-rkujawa: {19} sudo usbdevs
addr 1: I/O error
addr 2: I/O error
( ... )
addr 127: I/O error

    It's the same if I don't connect any USB device.

    I suspect that this is software problem - being afraid that my 
laptop is broken I booted some linux livecd lying around (kernel 2.6) 
and USB was working flawlessly.

    - When running 3.0 kernel with ACPI enabled, everything hangs in few 
minutes. Completly. Hard reset is needed to make it work again. I'm not 
even able to drop into ddb. Maybe I could use debugger onver serial 
console, but this laptop doesn't have any serial ports... -current 
kernel with ACPI doesn't even boot. It hangs before IDE drives detection.

I've built my -current kernels approx. two weeks ago. Today I updated 
sources and rebulit it - nothing changed :[.


kernel confs:

Any ideas?

Thanks in advance
