Ole Holm Nielsen 2008-03-28 10:19:20 EDT Description of problem: The built-in SATA hard disk of the HP dc7800 desktop PC (with Intel Q35 Express chipset) is incorrectly configured, and disk I/O performance is more than 10 times lower than it should be. Users experience a very slow system. ![]() Hp Dc 7800 Bios UpdateWe test I/O performance by writing a large file to disk: # time dd if=/dev/zero of=temp bs=1024k count=50000 bytes (5.2 GB) copied, 978.086 seconds, 5.4 MB/s Another symptom of the problem is that DMA is turned off (and cannot be turned on): # hdparm -d /dev/hda using_dma = 0 (off) The fact that the disk is denoted as /dev/hda in stead of the expected /dev/sda is yet another symptom of the problem. We have installed Fedora Core 9 on the same hardware. FC9 detects the hard disk as /dev/sda, and writing a big file as above gives a disk I/O speed of 55-60 MB/sec. We have also built and installed the kernel.org Linux kernel version 2.4.26.2 on the RHEL 5.2 system, and this kernel fixes the problem as well. Hp Dc7800 Bios DownloadConclusion: The RHEL kernel 2.6.18-84.el5 (and older) doesn't support the Intel Q35 Express chipset correctly. The solution would seem to be backporting the support of Intel Q35 Express from later Linux kernels. ![]() Version-Release number of selected component (if applicable): RHEL 5.2 Beta (and any previous version) How reproducible: Always Steps to Reproduce: 1.
