I get the messages below when I'm trying to mount or unmount Lustre filesystems (ost or mdt) on a brand new server. The same OS with
the same patched kernel and the same Lustre version (1.8.5) has been running for months without any problem another server with different hardware
configuration.

The new server is an HP ProLiant DL380G7 with two hexacore processors, 12GB of RAM, four 7.2TB (5*2TB SAS RAID5) OSTs on two P812 controllers
(2 OSTs per controller) and eight 146GB SAS disks on a P410 controller (OS, MGS/MDT and external journals for the OSTs).
