I don't know if this should be considered a bug or not so help is appreciated. I have a sil3124 chipset PCI card flashed with base(non-RAID) BIOS. Connected to this card I have a sil4726 chipset 5 drive enclosure with up to date firmware. The enclosure has been configured using a Windows machine with 2 750GB drives in RAID 1. So a host PC should see 1 logical 750GB drive + configuration drive if my understanding is correct. I have tried many of the latest kernels but the drives are not detected correctly. At the moment I have just tried the latest fixes at upstream-fixes @ git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev.git Attached below is a dmesg log with the above specified kernel for the following action. 1) Boot computer 2) Begin recording dmesg log 3) Turn on sil4726 based drive enclosure 4) Wait for dmesg activity to settle 5) Stop logging At the end of the process I have no additional disks in /dev/sd*. Does anyone have any suggestions or any troubleshooting steps that I should try? What can I do to provide more useful information?
