Failure with booting of qemu_x86_defconfig in buildroot-2011.11?

1

I have built the qemu_x86_defconfig with buildroot-2011.11, the qemu-system-i386 version is 1.0.50 and I use the external cross toolchain of Sourcery CodeBench x86/x86_64 2010.09, but I encountered the following problem:

Linux version 3.0.4 (liunx@liunx-desktop) (gcc version 4.5.1 (Sourcery

Here is my qemu boot script:

qemu-system-i386 \
-m 256M \
-kernel images/bzImage \
-append "root=/dev/sda rw console=ttyS0,115200" \
-hda images/rootfs.ext2 \
-boot c \
-localtime \
-net nic,vlan=0,macaddr="12:34:56:78:9a:bc" \
-net nic,vlan=0,macaddr="12:34:56:78:bc:de" \
-net tap,vlan=0,ifname=tap0,script=./qemu-ifup \
-nographic

I also tried the qemu_arm_versatile_defconfig with the same qemu boot script, and it works very well, so I really can not understand what's wrong, and any tips?

Back in late 2011, we had problems with the IA32 CodeSourcery toolchain, but they should now be fixed.

Try to use:

root=/dev/sda1

in boot script as sda1 corresponds to the first partition of the sda.

Have you tried to disable SELinux as mentioned in this thread?? Perhaps it might fix it.
