Hi,<div><br></div><div>I&#39;ve installed Centos 5.5 (plus updates) in a machine with INTEL DP43BF motherboard.  In order to make Linux detect the PCIs I&#39;ve added the pci=assign-busses in my GRUB conf.</div><div><br></div>
<div>Everything runs fine but within less than 2 days of uptime the machine simply freezes (black console no connectivity).  This has happened more than one time so I&#39;m considering to be a problem. The memtest passed without a problem and the machine uses a compact flash (sandisk extreme III 4GB) as a disk.</div>
<div><br></div><div>I could only find the error messages in my /var/log/messages but those appear hours before the actual lock.</div><div><br></div><div><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
