Hello Klaus ;-)
Could you ask Alasdair wich dm devel patches should be added with kernel
2.6.12-rc5 ?
I noticed that in this kerenel release are added many dm devel patches.
Best regards and many thanks ;-)
Have a nice day
Hubert

The hardest part of the fix involves changing the sequence of
device-mapper ioctls that LVM2 uses, and that's a couple of weeks'
development work, now pencilled into the RHEL4 Update 3 timescale.
In the meantime, you can apply the snapshot patches in the -udm
tree and use 'dmsetup' manually to activate and deactivate snapshots
when lvm2 fails.
Patches 8 and 9 at:
ftp://sources.redhat.com/pub/dm/patches/2.6-unstable/2.6.12-rc2/2.6.12-rc2-udm1/
(Further patches are needed, but those two plus correct dmsetup use
should avoid machine lockups.)
