Hi,

I have tried applying the patches and each time I get simmilar errors:-

---------
can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|Index: drbd_receiver.c
|===================================================================
|--- drbd_receiver.c (revision 1438)
|+++ drbd_receiver.c (working copy)
--------------------------

I will try the kernel upgrade path and let you know the outcome.

Thanks,

George.
