"adb shell stop" & "adb shell start" cause system hang

[DG]

I am having issues running emulator on ubuntu machine, even on éclair
tip. My issue is that when I replace libc.so by libc_debug.so and
restart android framework using “adb shell stop and adb shell start”,
emulator hangs at “Android” screen.

Following are the steps I took to run emulator:
1. mkdir /local/mnt/workspace/0224tip+Emulator
2. cd /local/mnt/workspace/0224tip+Emulator
3. repo init -u git://git-android.mycompany.com/platform/manifest.git -
b éclair
4. repo sync
5. source build/envsetup.sh
6. choosecombo 1 1 2 3
7. make –j4
8. ./out/host/linux-x86/bin/emulator -sysdir out/target/product/
generic/ -kernel prebuilt/android-arm/kernel/kernel-2G_2G-qemu -data
out/target/product/generic/userdata.img
9. adb shell stop
10. adb shell mv /system/lib/libc_debug.so /system/lib/libc.so
(Problem is reproducible without this step)
11. adb shell start

Following are the android specific variables set on machine:

ANDROID_PRODUCT_OUT=/local/mnt/workspace/0224tip+Emulator/out/target/
product/generic
ANDROID_BUILD_TOP=/local/mnt/workspace/0224tip+Emulator
ANDROID_SWT=/local/mnt/workspace/0224tip+Emulator/prebuilt/linux-
x86_64/swt
ANDROID_QTOOLS=/local/mnt/workspace/0224tip+Emulator/development/
emulator/qtools
ANDROID_SYMBOLS=/local/mnt/workspace/0224tip+Emulator/out/target/
product/generic/symbols
ANDROID_TOOLCHAIN=/local/mnt/workspace/0224tip+Emulator/prebuilt/linux-
x86/toolchain/arm-eabi-4.4.0/bin
ANDROID_EABI_TOOLCHAIN=/local/mnt/workspace/0224tip+Emulator/prebuilt/
linux-x86/toolchain/arm-eabi-4.4.0/bin

I synced to the tip of eclair and gave a build for emulator:
1. source <android dir>/build/envsetup.sh
2. choosecombo 1 1 2 3
3. make -j4

once build was done for emulator, I ran emulator using following
command from <android dir>:
./out/host/linux-x86/bin/emulator -sysdir ./out/target/product/generic
-kernel ./prebuilt/abdroid-arm/kernel/kernel-2G_2G-qemu -data ./out/
target/product/generic/userdata.img

now the emulator comes up.

Now I run
1. adb shell stop
2. adb shell start

before 1st step, I cleared the ddms log so that I can get all messages
from 1st step i.e adb shell stop.
after 2nd step, emulator hangs at big android silver screen and never
comes up.

Any idea what mistake I am doing or how to debug this issue?

Thanks a lot,
DG

Sounds like a system crash, what does your logcat output? Look for a
system crash message.
