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?

Re: bacula server

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. Lets just say it is a probably a good thing the fedora box is remote so i cannot physically get to it.

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

what does FC5 x86-64 upgrade do with i386?
by Jack Howarth 16 Nov '06

16 Nov '06

I am still a bit unclear on what I should expect when attempting to upgrade a FC4 x86-64 installation to FC5 x86-64. Specifically, I have installed the i386 firefox and associated plugin rpms on the FC4 x86-64 machine using yum.repos.d entries of fedora.i386.repo, fedora-updates.i386.repo and fedora-extras.i386.repo (which are all disabled by default). How exactly does the anaconda react to the presence of the i386 rpms on a x86-64 machine? Will they be removed in favor of the x86-64 rpms form FC5? Also I have asked this several times here before but never gotten a response. How are people keeping their i386 rpms properly updated on a x86-64 machine? So far I can see no other option than to manually reinstall the i386 packages with yum (using --enable-repo) when new versions are available. However that is a very painful process and makes it very difficult to keep the i386 rpms on a x86-64 machine properly updated. Thanks in advance for any comments. Jack

kudzu and modems.
by akonstam＠trinity.edu 26 Sep '06

26 Sep '06

I can't understand the behavior of kudzu in respect to my serial modem. After initial installation it detects the modem but after that it is ignored. What I mean is I can remove the modem and kudzu ignores the change, or I can remove the modem from the kudzu database and kudzu ignores the change. I can run: kudzu --class MODEM and kudzu will remove all my hardware from its database except the MOUSE but it still ignores the modem. How can I get kudzu to notice that I have changed, removed or added the modem? -- ------------------------------------------- Aaron Konstam Computer Science Trinity University One Trinity Place.
