[PATCH] Fw: [PATCH] bio_clone fix
[PATCH] bio_clone fix
Fix bug introduced in 2.6.11-rc2: when we clone a BIO we need to copy over the
current index into it as well.
It corrupts data with some MD setups.
[let me add: lvm setups, drbd setups,
any other device driver that happens to use bio_clone...]
See http://bugzilla.kernel.org/show_bug.cgi?id=4946
Huuuuuuuuge thanks to Matthew Stapleton <matthew4196 at gmail.com> for doggedly
chasing this one down.

I am not saying that this is definitely what you see,
but I do strongly suspect it.
upgrade the kernel to something >= 2.6.12.4.
