LAB problem - very strange

Hello,

I have two h2200 and have first installed LAB and Linux (in flash on the
pda) on one of my h2200s and it is working great. Then I tryed to do
exactly the same for the other one, but I encounter a strange problem with
LAB. I installed zImage-LAB-20060222.htc and after the first restart of
LAB it loads and boot's linux, but when I shut down linux and restart lab
I get the following error msg:

Uncompressing Linux................................

invalid compressed format (err=2)

 -- System halted


I can reflash lab and it again only works once, even if I haven't booted
into linux and have just pressed the reset button.

It would be great if you guys could help me.

Cheers,
Phil
