From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7 Description of problem: I have a onboard SATA controller in my HP DL140 G2 machine (RH certified hardware). The SATA disk drives are detected as /dev/hda and /dev/hdb when installed. They show poor performance (3 MBps) and the clock gets all out of sync, and sometimes does not boot at all with APIC IO timer errors. I have actually found a workaround for this problem, when I installed the system I did it through PXE boot and an NFS install and like that the disks were detected as /dev/hd*. But later I installed a IDE CD-ROM drive and after that the machine did not boot. After investigating more the SATA disk drives had jumped to /dev/sd* after installing the CD-ROM. I installed the system again with the CD-ROM drive attached and the machine performs as expected now. SATA Controller from `lspci`: 00:1f.2 IDE interface: Intel Corporation 82801EB (ICH5) SATA Controller (rev 02) Version-Release number of selected component (if applicable): kernel-smp-2.6.9-22.EL How reproducible: Always Steps to Reproduce: 1.Install a DL140 G2 machine or I guess a machine with the Intel Corporation 82801EB (ICH5) SATA Controller. 2.Have no IDE hardware connected. 3.Performance will be quite bad. Additional info:
I did an additional test, removing the CD-ROM and booting. The machine booted normally after doing that which I find a little weird. So I decided to see if the problem still existed when installing and disconnected the CD-ROM and went into a PXE/NFS install and sure enough my 2 SATA drives were detected as /dev/hda and /dev/hdb.
I have been able to install RHEL4 U8 to 2 different systems using the 82801EB ICH5 SATA controller, in both cases ata_piix driver controls the drives under /dev/sdX so I am closing this BZ out.
Well, I wonder why it works for David and not for us :) I have exactly the problem that a sata HD and CDROM are seen as ide and mounted as /dev/hda and /dev/hdb with Redhat 5.4! this is a Dell Optiplex 760 and dmesg says: NetLabel: Initializing NetLabel: domain hash size = 128 NetLabel: protocols = UNLABELED CIPSOv4 NetLabel: unlabeled traffic allowed by default PCI: Bridge: 0000:00:01.0 IO window: disabled.
