BUG: spinlock wrong CPU on CPU#1, fgBT878/1849 (Not tainted)
by Alan McIvor 17 Feb '07

17 Feb '07

Hi, I'm trying to upgrade a device driver from FC2 to FC5 and am running into the problem shown below. This is on a hyperthreading P4 3GHz running kernel 2.6.15-1.2054_FC5smp. It also happens using kernel 2.6.16-1.2096_FC5smp. There are 16 devices in the machine. For each there is a fgBT878 process, running at the max SCHED_FIFO priority. If I reduce the number of devices to 1 or 2, the problem doesn't appear to happen (i.e., with 16 devices the panic happens pretty much straight away, with 1 or 2 devices I have run for an hour). I have no problems with a non-SMP kernel. What sort of errors should I be looking for in my driver code?

Mozilla - Flash Player..
by Ted Gervais 17 Jan '07

17 Jan '07

Hi everyone. I am knew to the list and have Fedora Core 5 newly installed. Most things are ok but I can't get the plugin for Macromedia Flash Player installed. I have tried all the methods available to me and while Fedora tells me that the Flash Player is installed, I don't see it when I click on Help>About Plugins. I have tried making sure the Flash Player files are in ~/.mozilla/plugins, and /usr/lib/mozilla, and any other place I think it might be looking for it. No luck. I have also tried to install it manually rather than using the automated process. And still no luck. But in every case, Fedora tells me that the Flash Player is installed. Now, how do I tell Mozilla that it is installed.?? -- Ted Gervais Coldbrook, Nova Scotia Canada b4r1a7

Re: bacula server
by RYAN M. vAN GINNEKEN 03 Jan '07

03 Jan '07

Thanks again mostly u/we got it to work so far. However it is asking for a pile of dependancies. I know give a guy an inch and he will try to take a mile or km here in Canada. Is there a way to install without any gui stuff or mabey i am wrong mabey there is no gui stuff. Some of the dependancies for those dependancies are X11 related. I do not have any X11 stuff on this box it has no xwindows/gnome system and is minimum install Command prompt only. So before i go ahead and make a big mess of my faily clean fedora box do i really need all these or is there a way to turn some of them off. Thanks again and sorry about top post i think my clock was messed up not sure how it happend but should be fixed now. ----- Original Message ----- From: Paul Howarth <paul(a)city-fan.org> To: For users of Fedora Core releases <fedora-list(a)redhat.com> Sent: Tuesday, March 14, 2006 1:10:02 AM GMT-0700 Subject: Re: bacula server On Mon, 2006-03-13 at 17:11 -0700, RYAN M. vAN GINNEKEN wrote: > First off thanks to all for your tremendous help without it i would have probably given up on bacula by now.

VNC: Which desktop it displays
by Shane Presley 18 Dec '06

18 Dec '06

Hello, I'm running VNC (pre-installed) with FC3. My client/view is on Windows 2000. To configure VNC I modified /etc/sysconfig/vncservers VNCSERVERS="1:root" VNCSERVERARGS[1]="-geometry 800x600" And set a password. Then started the service "service vncserver start" Starts up fine, and I can connect with my viewer to port 5901. I'm new to Linux, so I'm confused about what desktop I am seeing. I know with VNC server on a windows server, you get the display that the local mouse/keyboard/monitor sees. There's only one desktop. With FC3, I seem to be getting a new virtual desktop. I guess that would be useful to run X applications. But is there a way to use VNC to display the exact same thing that my locally attached keyboard/mouse/monitor see? So if I change something remotely using VNC, the local monitor also displays my changes. Just as if I was at the console? Thanks Shane

Installing Python 2.4
by Mariano Draghi 13 Dec '06

13 Dec '06

In http://www.python.org/2.4/rpms.html there are RPM packages for FC3, and a Yum repository provided by python.org (hey! so far FC3 is the only distro with RPMs provided by python.org itself!) I'd like to know if anybody have installed these packages, and if they fit pleasently into FC3. As Fedora uses Python *heavely*, I don't want to break anything. So, it's safe to install this, or I'd be better waiting for an official update? (assuming there are plans for such an update...) TIA, -- Mariano

scim and transliteration
by François Patte 11 Dec '06

11 Dec '06

Bonjour, I would like to know if there is an input method in scim which could provide roman transliteration letters: I need vowel with macron, consonnant with upper and underdot etc. I have found "latin pre" and "latin post" virtual keyboard but they do not provide all composed letters I need. Is it possible to add some composed letters? There is also an "unicode" and "utf-8" keyboard: is there a configuration method of scim which could allow to define keyboard short cuts giving the letter corresponding to a code; for example, I define "Alt a" short cut with u+0101 and get a lowercase a-macron, "Alt A" will give uppercase a macron, and so on. Thank you for attention and (I hope) answer. -- François Patte UFR de mathématiques et informatique Université René Descartes http://www.math-info.univ-paris5.fr/~patte

Warning light on Fedora System
by WGregory 01 Dec '06

01 Dec '06

Thanks to the list, I am now able to play an audio sound and recording from my Fedora 5 box to warn out our night crew of a problem (play [filename].wav/ogg). I also would like to connect a warning light or strobe to the system to provide visual warning. In addition to lan, I have serial and usb ports available on my system. Does anyone know of such a product? And how to trigger it to alert from Fedora? Needless to say, also need way to turn if off from the Fedora.
