Title:
  psb_gfx boot hang on Atom N2600 (GMA3600 Cedarview)

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  psb_gfx causes kernel stall at bootup immediately after framebuffer
  initializes. Screen goes black and system unresponsive. Usual suspects
  - disable vt switching, console=tty1, nosplash, no plymouth, disable
  plymouth, hard set framebuffer mode - don't solve the problem. Problem
  also exists in mainline and vanilla upstream kernels with gma500_gfx,
  although gma500_gfx on 3.3rc5 gets slightly further in that it redraws
  the screen text after the framebuffer initializes at a rate of about 1
  line every 3 seconds. If you wait long enough, kernel kicks out stalls
  as follows (on 3.3rc5):

  ioremap error for 0x3f675000-0x3f678000, requested 0x10, got 0x0
  gma500 0000:00:02.0: GTT PCI BAR not initialized.
  gma500 0000:00:02.0: GATT PCI BAR not initialized.
  INFO: rcu_sched detected stalls on CPUs/tasks: { 0} (detected by 2, t=15029 jiffies)

  dmesg doesn't offer much insight:

  drm.debug looks like this before the stall:

  [     3.902515] Switching to clocksource tsc

  [    44.751817] Console: switching to colour frame buffer device 128x37

  Likely to be a big problem, as N2600 netbooks/devices are beginning to
  flood into the market.
