Oddities with my new machine: interrupt storms (hdaudio), DRM errors (i915) and gdm keyboard fail



Dear folks,

my new x86_64 (ASUS VivoPC VC62B) machine has arrived and I installed
NetBSD-7.1/amd64 on it. All seems to work fine but for some oddities:

- it has an interrupt storm on ioapic0 pin 16 for hdaudio0. It gives
  "hdaudio0: RIRB timeout" twice and then generates an sustained impressive
  201063 interrupts per second.

- when starting X it works fine but I can get "DRM error in
  hsw_unclaimed_reg_clear: Unknown unclaimed register before writing to ..."
  on fe scrolling too fast. It can freeze the display for a while but
  generally moving the mouse a bit unfreezes it. For details, see attached
  dmesg.

- xdm works fine but gdm eats my keyboard. Key presses and releases are not
  registered correctly giving a near-dead keyboard. I have no idea why!

Ideas? Has any of these problems been fixed already in -current or the
upcomming 8.0?

Thanks in advance,
Reinoud
