it was in Martins git-repository (see above link, different branches for 
2.6.32, 2.6.35 and 2.6.36)

for example the commit for kernel 2.6.36

http://git.kernel.org/?p=linux/kernel/git/mkp/linux-2.6-
mkp.git;a=commit;h=069bd9391faf24da0c4311b4d799f8aac3986efd

ok, i will do this. But it looks specific to md-raid (dm-md-fix-
merge.patch) and i don't use MD-raid (i'm use HW-Raid from promise stex 
driver).

i will try Martins patch too.  I don't want to wait until the patch 
arrives the mainline kernel (i need the pc and there is no workaround 
available).
