Do you say, that on other Snapdragon hardware msm-2.6.35 tree with console=tty works fine and there is no error? > BTW did Dell release a kernel for Streak? They might already have a > workaround in their kernel. Yes they did: http://opensource.dell.com/releases/streak/ (This is where I ported the changes and drivers from) But this kernels have exactly the same problem. framebuffer driver works fine accessed from userspace, but breaks on displaying kernel boot messages. Right after the message: Console: switching to colour frame buffer device 60x50 I will try to retype the OOPS message, but it's hard - it scrolls out of the screen ;-)
