Is any chance to solve that issue ? Is any workaround ?

So the problem exists on 2.6.28.9 and not on 2.6.28? That's strange since the
only reiserfs change is this one:
--- a/fs/reiserfs/inode.c
+++ b/fs/reiserfs/inode.c
@@ -2556,7 +2556,7 @@ static int reiserfs_write_begin(struct file *file,
}
index = pos >> PAGE_CACHE_SHIFT;
- page = __grab_cache_page(mapping, index);
+ page = grab_cache_page_write_begin(mapping, index, flags);
if (!page)
return -ENOMEM;
*pagep = page;
I'm surprised that reiserfsck doesn't come up with anything. This is a problem
where it's seeing an invalid bit on disk. Either that or memory corruption.

On 2.6.25.4 works stable.
Upgrade to 2.6.28.7 and 2.6.28.9 causes kernel panic[...]

Ok, I'm going through the reiserfs differences between 2.6.25 and .28. Can you
try to reproduce with 2.6.30?

isn`t this an invalid bugreport, as DRBD is NOT part of the mainline kernel?
i`t not against drbd - i whished it was in mainline (please vote for that on
lkml, as there is discussion going on about inclusion) - but until it IS, this
is an unsupported secnario. isn`t it ?

It seems that problem is related to external journaling and network device. I
was able to reproduce problem on iSCSI device (using external journaling).
Currently I have to abandon external journaling: "standard" reiserfs works
over my drbd without any problem...
