Summary: ndis-bridge hang host

Initial Comment:
I report this problem in #2445837
Unfortunate, the problem live also.
I try the autobuild-20090210, it hang also.

step:
1. Boot your linux with cmd
set COLINUX_NO_SMP_WORKAROUND=N
colinux-daemon.exe -t FLTK cocon=116x36 kernel=vmlinux mem=500 cobd0=..\root_fs cobd1=..\swap_fs eth0=ndis-bridge,"本地连接" setcobd=async root=/dev/cobd0 ro

2. login to linux
3. execute 'halt'.
Now, you will found process 'colinux-ndis-net-daemon.exe' can not halt, and host can not do manything(include close system), you must hard-reset your PC.


btw: another info when I use my build-20081209, it work fine, and when I replace vmlinux in build-20090211, it will report "colinux: BUG at /develop/build/linux-2.6.22.18/block/elevator.c:780"
I do not known what's wrong in kernel patch.

Message:
1. My host is Windows2000 SP4, 1GB RAM, Core Duo 2.8GHz
2. When I set 'COLINUX_NO_SMP_WORKAROUND=Y', the
'colinux-ndis-net-daemon.exe' can be close, but 'colinux-console-fltk.exe'
can not, and hang my system also.
3. use cmdline 'init 1', I look 'colinux-ndis-net-daemon.exe' running, and
I got same as (2)
4. I look the info below:
io scheduler noop registered
io scheduler anticipatory registered (default)
io scheduler deadline registered
io scheduler cfq registered

Message:
What is the host system? Windows XP or Windows 2000?
Does it hang with COLINUX_NO_SMP_WORKAROUND=Y ?
Does it hang, if you boots without using network? For example by adding
"init 1" to the kernel parameters (starts in runlevel 1).

For the elevator.c:780 you have changed the IO Scheduler to CFQ?
"setcobd=async" does not work in conjunction with "elevator=cfq".
I have added as separate bug artifact #2588147
