Package: lvm-common
Version: 1.5.17
Severity: normal

Hi,

on the nightly backup run which creates for a consistent view of the
filesystem LVM snapshots lvcreate oopsed yesterday. After the oops the
number of processes and the system load began to increase permanently
until after approximately two hours the system got unreachable exept for
ping replys. My monitoring also says that the load was entirely due to
iowait.

After a hard reset I discovered the following syslog entries:
