Hmm.. no luck on top of d5f6545934c4 ("qnx4: work around gcc false
positive warning bug") with the patch. Nothing gets printed after
"Starting kernel ...". Without the patch boots fine.
Here's the full /proc/cmdline from running system:
console=ttyO2,115200n8 debug earlyprintk=ttyO2,115200n8 mpurate=auto
buddy=none camera=none vram=12M omapfb.mode=dvi:640x480MR-16@60
omapdss.def_disp=dvi root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait
