Bug#610507: reproduce #610507 with Wheezy + fix with blacklist

["Aeschbacher, Fabrice" <Fabrice.Aeschbacher@siemens.com>]

Hi, 

I can reproduce #610507 with Wheezy and kernel 3.2.0-4-amd64 on the same hardware (Intel Xeon W3530 4 cores)

The following command eliminates the timeout:

# echo 'blacklist ipmi_si' > /etc/modprobe.d/ipmi.conf

With kind regards,
