Hello list,
This is odd - I'm having a RHEL 6.2 system die on shutdown while trying to
shut down the loopback interface:
Shutting down system logger: Ý OK ¨
Shutting down interface eth0: Ý OK ¨
Shutting down loopback interface: Ý OK ¨
INFO: task vgs:2171 blocked for more than 120 seconds.

Has anyone seen this?
Just a bit more info - I did add an eth1 using a 2nd NIC to another
VSWITCH with no OSA (for a "private interconnect"). Not sure if that's
pertinent, but I believe it started after I added that. Also, this is a
clone - the golden image does not die like this. After reIPLing, here's
the output of ifconfig and uname -a:

(Hmm, now I halt a second time and it shuts down normally - strange.)
It has the undesired effect of the virtual machine not logging off on halt
:((
Any help will be appreciated
