Description of Problem:
i have already worked with the RHN Support on this problem and they told be to
contact bugzilla. you can read on the problem at Service Request 210756.
there is a sysreport at the service request.
please get on the problem.
complete machine is locked up, no more working for many seconds during the whole
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. filesystem read/write. (e.g. scp is enough)
That's often a sign that your disk is not running in DMA mode. Also, the
current errata kernel has _far_ better interactive performance under load.
Please reopen this request if the errata kernel still performs poorly, and you
have determined via "hdparm" that your disks are all using DMA.
