Re: [Qemu-devel] 2.6.21 kernel on emulated/real Malta board

[Stefan Weil]

Hi,

2.6.21 with patches from OpenWrt works for AR7 with
CONFIG_EARLY_PRINTK and real hardware or QEMU emulation.
Maybe I can compare it to Malta tomorrow.

Perhaps some environment settings are missing for
early printk and result in a crash...
