Hello,

I'm getting these two errors when booting DT linux v3.19-rc5 in n900 qemu:

Hello,

instructions how to use qemu for n900 I wrote on uboot ml:
http://lists.denx.de/pipermail/u-boot/2015-January/200171.html

Just replace u-boot.bin file with bootable kernel image zImage. 
In above instructions is u-boot.bin booted as regular kernel 
image by Nokia bootloader. If you do not have qflasher (for 
generating qemu MTD nand image) + Nokia bootloaders and you are 
OK with Nokia license I can provide you needed binaries.

Kernel config which I used you can find on:
https://gitorious.org/linux-n900/linux-n900/source/v3.19-rc5-n900:arch/arm/configs/rx51_defconfig

There is also v3.19-rc5-n900 branch which contains some patches:
https://gitorious.org/linux-n900/linux-n900

I don't see these on real HW.
