Bug Description
working on 2012.05 source code from qemu-linaro git repository,
My target machine is 'beagle' softmmu mode running on i386 ubuntu 12.04 host
I turned on the tiny code interpreter, qemu hangs right after when the linux kernel finished to boot and tried to run a user mode process. (it's okay without tci configured)
1. configure options:
configure --enable-
2. qemu command line:
$QEMU -M beagle -m 256 -clock unix \
-monitor stdio \
-drive file=${
-serial telnet:
-usb -s
3. guest console
U-BOOT --> kernel booting messages
...
[ 7.173797] VFS: Mounted root (ext4 filesystem) on device 179:2.
[ 7.213439] devtmpfs: mounted
[ 7.226928] Freeing init memory: 228K
Connection closed by foreign host. --> QEMU hangs at this point.

I'm afraid we don't really have much spare resources to hunt down bugs in odd configs like using the TCI interpreter. If you need a fix for this then I think your best options are (a) investigate the bug yourself or (b) try to reproduce a similar problem on a machine model supported by upstream QEMU so you can report a bug upstream. Sorry I can't be more helpful here...
