Subject: Problem with Sil3124 under Mac OS X Server
From: Rodney McGee
Date: Mon, 25 Jun 2007 23:32:18 -0400
To:

Card: Sil3124 - 4 port
OS: Mac OS X Server 10.4.10
Model: Xserve w/ Dual 2.3 GHz PowerPC G5
Memory: 2 GB DDR SDRAM

Problem:
I have a external 1 TB eSATA device. The drive is briefly detected as being of zero size and then disappears from the Finder and Disk Utility and sometimes there is a kernel panic. However, the problem is limited to Mac OS-X Server, because I have tested it with OS X with no problems with the same hardware. I guess the driver needs a small change to be compatible with OS X Server.  I have included the kernel panics and a screenshot from Disk Utility. Before installing the driver the system was completely stable.

Config 1--
Card: Sil3124
OS: Mac OS X Server 10.4.10
Hardware: Xserve G5
*Results: Fail*

Config 2--
Card: Sil3124
OS: Mac OS X 10.4.10
Hardware: Xserve G5
Results: Success

Config 3--
Card: Sil3124
OS: Mac OS X Server 10.4.10
Hardware: Powermac G5
*Results: Fail*

Config 4--
Card: Sil3124
OS: Mac OS X 10.4.10
Hardware: Powermac G5
Results: Success

I have tried all the following drivers: 2.0.3, 2.0.1, 1.4.1 ,1.1.0 w/ the same results.

To uninstall the driver between trying different version I used this script:
#!/bin/bash
sudo rm -rf /Library/StartupItems/SiCoreService
sudo rm -rf /System/Library/Extensions/SiliconImage3124.kext
sudo rm -rf /Library/Receipts/SiI3124*

Is there any other information you might need? I can send you anything.

Thanks,
