I wanted to try Fedora 12 Live/KDE on a newly-bought Fujitsu Esprimo P1500. Booting with no kernel options would just freeze the machine. After some random experimentation, I added the option "nolapic" and got a seemingly working machine. However, only seemingly, as it turned out that only one of the processor cores was working (the processor is a "Pentium(R) Dual-Core CPU E5300").

View 5 Replies View RelatedI recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.

When i viewed the cpuinfo file (using command: vi /proc/cpuinfo ), i found that there are listings for 4 processors( i.e 4 sets of listings each one starting with item : processor - 0 ; processor -1 and so on..). Each of them have similar data among which one is "cpu cores" which is 2 for all.. How do i make sense of this data.. 4 processors with 2 cores each ? Also, what could be this hardware be classified as : dual core? quad core ?...
P.s: each of these processor listings also have an item called "siblings" which is 2 for all... Just thought i'll include this here because i felt it may be relevant to this question..
I just loaded F14 on an old Dell Dimension 3000 with a dual core processor but only one is showing. Here's the output from top:

We have a small cluster of 20 HP systems, all running CentOS 5.3 in an NFS-root environment. Half are quad-socket, quad-core Xeon E7340 @ 2.40GHz (total 16 cores), the other half are 8-socket, quad-core Opteron 8354 (total 32 cores). All systems have a Mellanox Infiniband adapter ("Mellanox Technologies MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE] (rev a0)")
With kernel 2.6.18-128.1.6.el5, infiniband works fine on all systems.
With the update to kernel 2.6.18-164.11.1.el5 (and both types of node running the same NFS-root image), the 16-core Xeons still work fine. Infiniband no longer works on the 32-core Opterons. Specifically, either the ib0 interface fails to appear, or it does appear but when configured with an IP address, doesn't actually work. In either case, loading the IB kernel modules takes a long time, but I haven't instrumented the load script yet to see which module, if any, is at fault. More errors listed below.
However, if I tweak the BIOS of the 32-core systems to reduce the per-socket core count to 2 (so effectively 8-socket, dual-core, down to a total of 16 available cores), Infiniband starts working again. Putting it back to 32-cores makes it fail. Booting the older kernel makes it work again. In summary: old kernel, IB works on all systems. Newer kernel, IB only works on 16-core systems.
Updating the IB firmware from 2.5.0 to 2.7.0 (latest available) doesn't help. I also did a full 'yum update' to make sure that libmlx4, openibd all other associated packages were up-to-date. Doesn't help either.
Some errors that appear on 32-core nodes:
ib_query_port failed (-16) for mlx4_0
ib_query_port failed (-16) for mlx4_0
mlx4_core 0000:04:00.0: SW2HW_MPT failed (-16)
mlx4_core 0000:04:00.0: SW2HW_MPT failed (-16)

I need to set the CR4.MCE bit for all the cores on my system (4). I'd like to write a linux kernel module for that, but I am not sure how to proceed: How do you sequentially access all of the CR4 registers? I have read the Intel manuals and they describe a way to initialize each core, but this is done in the bios.

View 2 Replies View RelatedI have created a virtual machine of a system running Fedora Core 4 and I need to upgrade it to Fedora Core 10. Based on what I have read, it iis possible so I started theupgrade process. I get an error message saying that /dev/hda6 (my root paritition does not exist) even though it does.
Does the installer need to read a label from /etc/fstab? I executed tune2fs -L / /dev/hda6 amd ,and added LABEL=/ for the corresponding entry for fstab. but the FEDORA CORE 10 is still giving the same problems for the installation process. Should I upgrade to an intermediate verson like Fedora Core 7 first?

View 3 Replies View RelatedWhen I mount Debian 8 live into VMWare Player 7.1.2 64bit, it works awesome with and without graphics acceleration enabled i.e I can get into the desktop and all that.
But, when I installed it, the reboot is just a blank screen. I am not sure how I can proceed from now.
I am on Windows 7, 64bit Ultimate.
My first upgrade attempt to 9.10 ruined my install - there was no return and as 9.10 would not install either, I reinstalled 9.04 and everything was as expected.I decided to wait for 10.04 hoping the issue had been solved - unluckily it has NOT. Neither Live CD 9.10 nor 10.04 work. New Mint does not work either - to closely related to Ubuntu, but Suse live CD does. Played around with findings from different threads - like taking out "quiet splash --" and adding modprob parameter to no avail Prime suspect is HD and HD controller (ATA/PATA) - but I could not nail it.
View 3 Replies View RelatedI have this problem where the 10.10 LiveCD 64-bit works (as in I get full resolution display and no video issues at all). But after install, the OS boots successfully but there's no display. I know it's successful because I was able to login in the dark (sound works).
Here's what I have:
HP m9340f (NVIDIA GeForce 9500M GS with HDMI)
46" Sharp connected via HDMI
Windows 7, works fine.
Here's what I tried with no luck:
1. CTRL-ALT-F1 still doesn't show anything on screen, no terminal
2. Connected via VGA
3. Connected another 17" monitor via VGA, rebooted
4. Added vga=789 in grub before booting
The weird thing is that I had 10.04 before and it was working for a while then it suddenly stopped working. I figured I'd wait until 10.10 but I now have the same issue. I haven't tried 32-bit... I can give that a shot in a bit.
I was running 10.04 with no problems. Upgraded. I may or may not have lost power before the upgrade was finished. Now my system locks out the keyboard and mouse on the login screen...nocapslock light or anything, but I know it's still running because the clock at the bottom increments once per minute. Booting safemode does not help, it simply hangs at some point on the scrolling black screen instead.I can boot 9.04, which is still installed on another partition, just fine.Is there any way I can boot to a terminal and try running apt-get again, to see if I can fix whatever's wrong?

I have tried openoffice but the mail merge is a nightmare to use and when eventually I managed to get something out of it instead of one page linked to a database it produced a separate page for each plus a blank page! I did manage to do something with openoffice database using a form letter but that was also a nightmare to do!
I tried Koffice which is supposed to have mail merge but nothing appeared on the Tools menu as the manual says it should. At the moment I am using MS office 2003 under Wine which works fine and does exactly what I want, only thing I don't seem able to do is install any of the service packs, any suggestions for that? Preferably I would like a Linux based word processor, does anyone know of one that has functioning mail merge?
A friend is trying to rescue some files from his computer because Windows won't boot, so he's making a Live CD.

I checked out the dell website for a cheap machine to run it on (I don't need high performance - just a personal file server running a few hard drives, and a web/mail server). I noticed that they have some cheap models in their server line that are as cheap as a desktop. Compare:

The main difference I see between the desktops and the servers is the use of the Core or Xeon processor, and also, the servers tend to have lower RAM.if I am looking for value, should I opt for a low end desktop or a low end server to run a personal server? Also, what advantage does the Xeon processors and Dell server line have over the desktop models that make it better for running a server?
Just a quick question. Does Kubuntu Karmic support core 2 E8500 out of the box or do you need the SMP kernel?
