similar to: Strange content in the kernel dmesg traces [SOLVED]

I am experimenting with the kernel (as some of you may know), and I have added a whole slew of traces in some relatively sensitive code in the lower levels of the page cache and i/o functions. Most of this tracing not only works but is highly revealing as to what the kernel is doing and why. However, I am now getting this odd content in the trace log (dmesg), and I cannot figure out what it is

I rebooted my machine this morning and now instead of running normally, my GLMatrix screen saver flashes as it repaints the screen, more and more noticeably as the screen fills up with glyphs. I didn't change ANYTHING and this was not happening before the boot. Anyone have any ideas why this might be? Thanks. Mark Hull-Richter, Linux Kernel Engineer DATAllegro (www.datallegro.com) 85

I went to enable samba on my home machine, which has a largely plain vanilla install of CentOS 4.4 Plus, and the smbd and nmbd files are missing. As you may know, this makes it rather difficult to run samba. For some reason, the winbindd binary is present, and rpm reports: samba-common-3.0.10-1.4E.11 samba-client-3.0.10-1.4E.11 as present. So how do I retrieve the missing samba binaries/ Do

I installed the kernel-2.6.18-8.el5.src.rpm today and went to build it, but it fails with this error: $ rpmbuild -bp --target=`uname -m` kernel-2.6.spec Building target platforms: x86_64 Building for target x86_64 error: Failed build dependencies: unifdef is needed by kernel-2.6.18-8.el5.x86_64 I double checked and this appears to be the latest kernel source rpm on centos/5.0/os/SRPMS.

I'd like to point out that overall I am quite pleased with CentOS 5, although I am having more fun with it than I did with 4.4 and I knew less about CentOS then (duh). Most things seem to work fine, including a relatively smooth installation from the DVD image I downloaded, although the number of screensavers I can see (and this could be related to the ATI/dual head problem) is pathetically

I just bit the bullet and installed CentOS 5 on my work desktop, and although I have two monitors and a card that supports them, I cannot get the display configuration to work with both as a continuous (spanning) desktop. I have tried using the correct (autodetected) monitor type (digital and analog), a generic LCD with 1280x1024, nothing works. Every time I set the configuration, the X server

I've asked this almost everywhere else, so obviously I only find out about this list now (my doing, too). I am running VMWare Workstation on top of host CentOS 4.4 Plus on a Dell Precision 390 with 2G of main memory. Under VMWare, I am running a Windows XP guest OS. I have a similar setup at home except that the hardware is a little different but the memory and the setup are the same, and

I recently added a Seagate 400Gb SATA drive to my system, and it has been behaving strangely since I put it in. for one thing, the BIOS S.M.A.R.T. came up with a warning the last time I booted with it enabled, saying that I should backup my data and replace the disk (!). I still have not made any irreversible data transfers to this drive, and I have some time yet to take it back, but I'd

Hi, George sent a patch on this problem before, but it was not completed. This patch makes libxl use xenbus to communicate with xenstored if libxl cannot open a socket. There''s a place that does not close fd in the case of failure, which is also fixed in this patch. -----------------------------------------Patch------------------------------------------------------ diff -r eff592364826

I had to reboot my work machine today, and it came up in text mode (!). I did an init 5, but that had no effect (wrong command?). I killed the three gdm processes, and voila, X server mode. Where do I look to find out what is not right here?

For the interest of all concerned: The 32-bit version of Seamonkey works perfectly with the flash plugin. I haven't tested others yet, including the acrobat reader, but I have much more confidence that problems encountered there will be easily soluble. Thanks to all who contributed, especially Jim Perrin, who gave me the critical clue as to what was not working. -- Mark Hull-Richter

I could be mixed up here, but I have mplayer working perfectly at home in CentOS 4.4, but I just built it here at work for CentOS 5.0 and it doesn't produce any sound. My h/w: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) Dell Precision 390 Intel Pentium 4 3.00GHz 2Gb RAM The sound from Adobe/Macromedia flash player works fine (in

Probably a stupid question, but here goes anyway. Are there any other screensavers available besides the four supplied in the release? Or is there a way to use the ones that came with 4.4 in 5.0?....

This may be off topic, but I'm not sure where to go - been to Gnome help and google - nada (wrong search?). I have CentOS 5 on both my work and home machines, with Gnome 2.16.0 (default, straight out of the box, so to speak). At work I have two 17" FP monitors on an ATI FireGL V3400, at home I have one 19" CRT on an nVidia GeForce7100gs. When I use alt-tab to switch windows at

I have been studying this for the last several days, and the one thing that leaps out at me is that the page cache always flushes one page at a time. Always. To some extent, there is justification for this - what has to happen for each page that gets flushed depends in part on what file system is being written to and whether or not there is a function for that file system to handle the pages.

As usual, virtually every printer on the market comes with Windows, and sometimes Mac OS, drivers for the printers, but they almost never come with Unix/Linux drivers. This time Google was not my friend. I got a pointer to a drivr, dommon<something>mp160.ppd that doesn't appear to exist anywhere on the web, and there are two driver files from Canon Asia that want a lot of i386

How necessary is it to run this gem on a desktop with a constant power supply? It doesn't seem to be all that useful, except if there's some significant power consumption advantage to lowering the cpu speed. Doesn't the CPU run at full speed unless throttled down by temperature, or is that what this thing does (for desktops)? Thanks. Mark Hull-Richter, Linux Kernel Engineer

I have begun to notice that the smartd stalls my machine's boot process for as much as 2-3 minutes while it is coming up. I have the BIOS SMART function enabled, and I removed the bad SG400GB drive from the box yesterday, but I think this goes back farther than that. Why does it take so long? Is the BIOS SMART involved in this (and how)? Also, sendmail and sm-client take 30s-2m to come up

I have the Adobe (Macromedia) flash player installed on my CentOS 4.4 x86_64 system, but when I try to play a flash movie in SeaMonkey (or Firefox - doesn't matter) I get no sound. I'm using the nspluginwrapper 0.9.91.4 to make it work at all, but there's no sound. All my other sound devices/players work just fine, even my Windows guest on VMWare Server. Any ideas/suggestions? Yes,

Not at all clear on what happened. I haven't downloaded my mail from gmail into Evolution for a couple of days, and today I changed my gmail password. Even though I told Evolution to forget my passwords and had to reenter them, I am unable to receive any email from the server. I get a quick "retrieving Pop summary" and then the window vanishes and nothing gets downloaded. When I
