I'm new on mips world, and new to the list. And i'm not pretty sure if this is the correct one to send this question.
I'm testing vmlinux-3.0.0-1-4kc-malta kernel, on qemu-mipsel. I run it with this line:
./qemu-system-mipsel -M malta -m 128 -cpu 4Kc -kernel $KERNEL -hda debian_wheezy_mipsel_std.qcow2 -append "root=/dev/sda1" -nographic
This same line, but running it with $KERNEL=vmlinux-2.6.32-5-4kc-malta works fine. (yes i update from squeeze)
