Subject: Problem: initrd boot failure on QSD8250

Hi.

I am porting msm-2.6.35 kernel to Dell Streak. I ported required
board-qsd8x50.c changes and most Streak hardware drivers from 2.06 Dell
release and the kernel is booting.

The problem is that it breaks on starting init from initrd, which is not
accessible. I have no idea what could be wrong. Maybe you could help me?

If you're interested in the kernel source it's on:
http://gitorious.org/streak/kernel and I'm using streak_defconfig to
build.

CONFIG_CMDLINE="init=/sbin/init root=/dev/ram rw initrd=0x11000000,16M console=tty mem=88M"

and the end of kernel boot looks like this:
[...]
