Package: mdadm
Version: 2.6.7.2-3
Severity: important

*** Please type your report below this line ***

Every time mdadm is executing its automatic data-check my system will
receive multiple soft locks, creating a temporary dos on my server.
Please see the attached file with the dump of the relevant syslog/kernlog.

I don't think I did anything special on my system or used out of
ordinary set-up. The soft lock happen on a production server that need
to stay secure and running. Any idea's why this problem is occurring?

Thanks in advance,
