ata_piix/libata - dma for ide dvd question/status
by Jarosław Górny 29 Oct '06

29 Oct '06

Hi, First, I'd like to say that I know that the question is not laptop specific, not even FC-specific, but I think there's a chance that someone can at least show me a right place to investigate further. To the point: I use FC5 on Dell Inspiron E1505 (vel 6400) with ICH7 chipset. It has SATA harddisk and IDE DVD drive[1]. CD/DVD burning is slow as well as playing DVDs, because DMA for this drive is turned off and it's impossible to enable it[2]. There are some tips (rather old, for kernels<2.6.13 AFAIK) around. Eg. adding 'hdc=noprobe' or 'combined_mode=libata' to kernel boot command line - that makes dvd drive to work in scsi-emulation mode. And this is where my questions go: 1. What is the current status of ata_piix/libata, is there a work going on to make it possible to enable DMA for IDE drive in native mode? 2. If scsi-emulation is still required to get reasonable transfers, what is the right way to set it up? regards, [1] 00:1f.2 IDE interface: Intel Corporation 82801GBM/GHM (ICH7 Family) Serial ATA Storage Controller IDE (rev 01) [2] <code> [root@moonstone ~]# hdparm -d1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) </code> -- Jaroslaw Gorny

Speedstep doesn't work on Centrino notebooks for Fedora Core 6
by Julian Yap 27 Oct '06

Hi, I have a Dell Inspiron 6000 notebook. I'm running a Intel(R) Pentium(R) M processor 1.73GHz CPU. I noticed during boot up, I get an error that can be reproduced when I try and start up the cpuspeed service. # /etc/init.d/cpuspeed start FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.18-1.2798.fc6 /kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device I've noticed that Fedora doesn't include the speedstep-centrino.ko module. Normally it would be located in: /lib/modules/2.6.18-1.2798.fc6/kernel/arch/i386/kernel/cpu/cpufreq/ Would this be the issue? There's a few bugs in Bugzilla if you search for acpi_cpufreq in Summary. This bug prevents the CPU from stepping down the lower speed (thus running all the time at the full speed). Regards, Julian

Cpuspeed worked perfectly since the first FC5 kernel and now with 2.6.18-1.2200.fc5 too. FC6 broke this success :( -- BÉRES László RHCE senior IT engineer, trainer

Any help is appreciated. I have to mention I see similar behavior of my HP laptop when it's resurrected from software suspend sometimes even on FC6. CPU load is at 100% immediately after waking the laptop up. Did anyone from you experience similar problems? Is there known any workaround? Thanks, Jindrich

Full screen video on Thinkpad T41p
by Joe Desbonnet 20 Oct '06

20 Oct '06

Shortly after installing FC5 on my T41p (ATI FireGL) I was able to get mplayer to play full screen video (pressing the 'f' button). Watching video was one of the last few reasons I had for rebooting into Windows so this was cool. I recall a flame war on the devel list about some upgrade (I think it was to X.org) which was going to break ATI drivers. I signed off the list at that point. Sure enough, shortly thereafter a "yum upgrade" degraded my machine so that full screen video nologer worked (I now just get a huge black border around the tiny video window when I press 'f' in mplayer). I don't know enough about X.org, Xv, mplayer etc to troubleshoot this problem. I don't even know what info I should post here to help diagnose the problem. Any troubleshooting tips would be greatly appreciated. Joe.

Hello!! I had installed the last version of Ferora Core in a HP pavillon dv6000 (laptop) and the x system doesn't work. When the first sesion ends his loading i recieve as result a black screen and I can't do anything I gues the driver is not working and i have the lastest driver from NVIDIA but I don't know how to install it because i don't have access to a text mode. My video card is a NVIDIA GeForce 7200 Go.

FC6 and laptops -- comments anyone?
by Joe Desbonnet 12 Oct '06

12 Oct '06

Any comments on FC6 and laptops based on the last test release? I haven't had time to experiment myself. I have mixed feelings about FC5. It started off fine and progressively got worse (Thinkpad T41p compatibility wise) as the updates were applied. Joe.
