Public bug reported:
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

dmesg doesn't offer much insight:
