Drive dropped again with this patch!
+ the kernel freezed.
(I will try to get more info...)

Hmm too bad :-( it seems it still doesn't work, sorry for that
I suppose the kernel didn't freeze immediately after disabling the drive
or you wouldn't have had the chance to cat /proc/mdstat...
Hence dmesg messages might have gone to /var/log/messages or something.
Can you look there to see if there is any interesting message to post here?
Did the COW device fill up at least a bit?
Also: you know that if you disable graphics on the server
("/etc/init.d/gdm stop" or something like that) you usually can see the
stack trace of the kernel panic on screen when it hangs (unless terminal
was blank for powersaving, which you can disable too). You can take a
photo of that one (or write it down but it will be long) to so maybe
somebody can understand why it hanged. You might be even obtain the
stack trace through a serial port but that will take more effort.
