Summary: scsi disk disconnects while creating an ext3 filesystem

Initial Comment:
I'm trying to make a mkfs.ext3 /dev/sda1 , while sda is scsi0=\Device\Harddisk2\Partition0 , an 8 GB USB Flash Pen drive. 
Before mkfs ends, the linux console starts complaining with lots of lines like:

sd:0:0:0:0: rejecting I/O to offline device

and after stop, /sda is no longer visible.

Tried with the 20091115 snapshot.

Message:
Before 20091115 snapshot I've had the similar error. With 20091115
everything works. But you and me have different preconditions:

      My case                                            Your case 
        Image on hard drive                             USB pen drive 
        Only while switching NT processes    ???
 
When I've tested new SVN revision r1293, have tried only "simple" magic: 
  1. Open "Process Explorer" window.
  2. While 'mkfs' working, mouse clicked at "Process Explorer" and back at
"colinux-console-nt".

For previous revision with this two conditions the error was reproduced.
With last revision - not. 

If you want somebody to reproduce this error, please write, what have you
exactly did while 'mkfs.ext3' worked? I mean your activity with mouse,
keyboard, or other user interface input devices, which coLinux console was
used and so on. Some NT processes may block (lock) devices for it's
"individual use" and it is erroneus to work with  the drive or partition 
at this time from coLinux. So your "magic" may be much complicated than my.

Then I can check three USB Flash Drives of various vendors: 4, 8, and 32
Gb.

Peter.
