Description Jason Juday 2005-01-11 18:10:54 EST
Description of problem:

Version-Release number of selected component (if applicable):
Update 4

How reproducible:
Repoduced numerous times on two systems.

Steps to Reproduce:
1. Have sata_sil drive/controller and 8GB memory.
2. Install Redhat EL3 U3 or U4
3. Reboot and see results!  Data corruption apparent during reboot.

Here is the detail. When using the Silicon Image SATA driver 
(sata_sil) under 8GB, data corruption occurs. With 4GB memory, there 
is no problem. You can verify this by removing 4GB from your system 
and reinstall RHEL3. BTW, we use RHEL3 Update 4 (AMD64 edition) for 

To support 8GB of memory under RHEL3, you will have to use SCSI or 
IDE disk. If you want to use the onboard SATA controller, the machine 
is limited to 4GB for now.

Comment 1 Jeff Garzik 2005-02-18 01:03:28 EST
Is this an EM64T (Intel-base x86-64) machine?

It's likely this is a duplicate of bug #132848.
Comment 2 Jason Juday 2005-02-18 14:18:19 EST
This was on an AMD Opteron system, not an EM64T.  We have already 
turned off the SATA controller, installed a SCSI card and SCSI drive, 
and the problem has gone away.
