Slackware :: Dell Server 2860 Hanging - Best Method Of Debugging Booting Process?
Dec 29, 2010
What is the best method for debugging the booting process? Is there a cheatcode (tried debug and failsafe). Slackware 13.1 with standard linux kernel 2.6.35.8. I having a problem with a dell server 2860 booting my build. It is hanging on
[Code]....
Booting my previous kernel 2.6.27.27(different disk with different initrd.gz) it loads the same as above but continues with
Code: loading iSCSI transport class v2.0-870 iscsi registered transport tcp I'm stumped it the problem is with the ata_piix module or the iSCSI transport module or some firmware I might be missing. I booted other pcs without issue.
Im using gdb for debugging my application.. I was able to debug child process(when fork comes) .. and in child process we have an exec call to .... So the problem is, when the control come to exec , the exec process is executing at a time... I could not debug the exec. process... error is stack curruption due to same frame So, is there any way to debug the exec process
I am working on Fedora core 4 with kernel verion 2.6.11.. I am running a Manager process which spawns child process. If a child process exits , the SIGCHLD signal is processed in parent process and it is forked again. When the parent process receives a SIGTERM signal it first tries to kill the child process using SIGTERM signal . if the child process dosen't get stopped then kill it using SIGKILL. Now,the Parent process sometimes gets hanged and the strace shows : futex(0x98535e0, FUTEX_WAIT, 2, NULL <unfinished ...>
I'm having problems booting up my Fedora 14 system. I see the Fedora splash screen (the one with the egg-like logo that colorizes as it loads); the logo fills up completely and then everything hangs - all I see is the egg logo, and nothing else is ever displayed. I also can't get to any of the ttys via the CTRL-F1 sequences.
I can boot into single user mode just fine. The install scripts all run just fine. The system itself is actually up an running, so I suspect this is either something in the KDE startup, or after init processes all of the start up scripts.
I'm assuming this isn't a startup script problem, because I see a "started XXX" message for every service in the rc.5 directory - in other words, all the startup scripts ran from rc.5.
So, how do I find out what is hanging? I'm not seeing anything in /var/log/messages, and pstree didn't tell me much about what init was doing.
I used to be able to follow inittab to see all the things it did at boot, but since inittab was stripped of everything it used to do a few releases ago, I don't know what init is doing anymore.
Every time I boot up OpenSUSE 11.3 it hangs at the same "position" for approximately 3 minutes and then continues to boot. Unfortunately I see no corresponding error log e.g. in dmesg output. Hence, I don't know what is the reason for that. Here is my dmesg output. The delay occurs at 20 seconds after beginning of boot process (line 1085). I also analyzed the boot process with bootchart. My computer: Notebook Lenovo ThinkPad R400.
I downloaded Ubuntu 10.10 and made created a DVD. When I started installing it, I'm not able to do it. I think its hanging. This is what happening: First I found a screen saying 'ubuntu 10.10' and it loaded for some time then I got a screen with a black color task bar at the top of the screen, then after some time it turned into white color and after some time it disappeared. Nothing else happened. I didn't find any pop-up window to start installation of OS..
But when I tried this in my friends house, I found that instead of 'ubuntu 10.10' there came 'Ubuntu' LOGO and it was little bit slow but a pop-up window opened to start installation.. Why its not coming in my PC.. my computer configuration : Windows XP, SP 2 256 MB RAM, 1.81 Ghz AMD 64 Athlon Processor 1800+ I want to shift my OS to Ubuntu completely.
Does anyone know how can one improve his debugging skills or how can one narrow down the problem and try to get to the solution ASAP.Or rather how once should approach a problem.I know this is a bit vague question but I want to know how you people approach?
I have some trouble booting the current KDE Live Cd (11.2) on my Laptop. I tried USB and CD both. The laptop hangs on the bios bootscreen and I cant select any further option like a boot device. No problem I have with an Ubuntu CD.
After recently looking around the Linux world, I decided that I would also like to try fedora. Primarily because of the BTRFS file system that I would like to try out while still having Ubuntu as my main OS. Normally, I'd just partition as usual as I would with any of my other OSs, however this is the first time I have tried to dual boot two Linux installs on two different file systems. Does anybody have a better method of going about this? Or to just go about it as usual and install on two different partitions? Also, I do not want to wipe the data from the computer as it is now. I have it all backed up, but I don't really want to go through the hassle.
i upgrade system from fedora10 to 11 when i start the system i got following error
Unable to keep input method running giving up to bring the process up because main input method process for SCIM rapidly died many time.See .imsettings.log for more details
.imsettings.log file contains this
imsettings information ========================== Is DBus enabled:yes Is imsettings enabled:yes Is GTK+ supported:yes Is Qt supported:no
Using slack 13 this started happening after my last 'upgrade-all' with slackpkg where I think it updated ssl and sea monkey. When I shutdown (fluxbox) it hangs at "starting up x11 manager" I have to ctrl alt del to get it moving again.
Less than 2 days ago i upgraded from slackware 13.0 to 13.1.Since then, I have not been able to use my laptop for more than 15-20 minutes, 'coz the KDE screen freezes all of a sudden without any crash report and in some time the screen goes blank with just a mouse pointer to be seen (Black Screen of Death?)I can do a CTRL-ALT-F* to switch to a console a continue, or reboot (using console) to get the X server started again. (CTRL-ALT-Backspace does not work either).
I'm thinking of setting up an old desktop (Dell Dimension 4300/512mb RAM/20g&80g hdd) as a media/file server and using Slackware 13 for it. I'm completely new to doing anything server-wise,it of background: I'm running current versions of Zenwalk and Vector on two different laptops, with the Zenwalk one multi-booting Vista and Ubuntu. The desktop in question is running XP and Zenwalk. I have DSL hooked up to a Linksys WRT (running dd-wrt firmware) for network. I'm not a noob, just not in my comfort zone. My goal is, in addition to setting up the server, to get more hands under the hood (so to speak) on improving my linux skills. It was a toss up between Slack and CentOS, and being very familiar with Slack-based systems, I'm going that route.
I am installling ubuntu on my old (2003) Dell D800 laptop with celeron processor, using a CD (burned at home). The installation process is hanging for about 24 hours now; it says "copying files..." with progress at 63%. The progress has not changed for about 10 hours.
I have a single hard drive on the machine (... noticed issues with dual drives on this forum, so thought I'd mention).
i'm a Chinese student, after I upgraded slackware13.1 to slakcware13.37, I find that I can't use the fcitx input method in emacs to type Chinese. One method is to comment parts of the font path in /etc/X11/xorg.conf-vesa file. I can use fcitx input method in the first emacs that I opened and then when I open a new emacs, I can't use fcitx input method and it indicates that the Ctrl+Space key combination is the Mark command. What's wrong with this problem?
I am after some suggestions on how I could change my mounting method to suit my needs.At the moment, I simply mount the device to a location as root.What I would like to do is setup automounting, but in a particular way. In particular, I would like it if when I put in a usb stick, it would be automatically mounted to say /media/usb1, and a second stick would be to /media/usb2, while an esata connected drive would go to /media/sata1
Even better would be if I put in the first usb stick and it was mounted at /media/usb1, it would *always* be mounted at /media/usb1, no matter what order I connected it to my computer in.I would also like to quickly ask about the difference about udev rules and HAL. At the moment I have only used HAL for my touchpad, and have not touched udev at all. What are the differences/advantages etc...
I have a system Intel sound chips running Slackware 13.1, full install. The sound is very low, whether through speakers or headphones. I have tried many things from searches online and especially here at LQ, including kernel module params, /etc/asound.{conf|rc|xxx} configuration, reading everything under /usr/doc/alsa..., etc... no joy. But at the end of the day I still remain unclear on any systematic method of troubleshooting alsa/chipset problems. So I am asking here for a systematic guide to troubleshooting and configuring alsa problems, including low sound in particular, but alsa setup and configuration generally.
I don't have any problem when I'm communicating with one client. The problem starts when I connect another client.The server eventually ignores the older clients and responds only to the latest one.The working mechanism is simple: Accept connections and print messages received from multiple clients.
Out of all the Linux I have tried, this is the only one which will hibernate and startup again properly. But it has no drivers for the rtl2860 wifi adapter. I am thinking of using NDIS wrapper, but it may stop hibernation working. I see a guide which I am going to try to follow, but has anyone out there got this adapter working and hibernation still works?
Our mail server keeps on hanging after a while. This happened after there was a breakdown in electricity supply and the server room air conditioners stopped working for almost half a day. We are not sure whether this is a server hardware problem or a coincidence with a break-in attempt or malware activity.
Following are the message from the server log code...
This was originally posted on the Ubuntu forum, but someone suggested it might be a hardware problem, so I've re-posted (and updated) here: Quote: Originally Posted by Girts My shiny new Dell has developed a booting problem over the last few weeks. The Dell splash comes on for up to 10 seconds, screen turns Ubuntu purple for up to 20 secs, then 'no signal' message is displayed by monitor and screen goes black. Hard drive light goes off, mouse and keyboard don't respond.
When the Dell engineer came to replace a suspected failing hard drive, he realised the noise was coming from the fan on the graphics card (ATI Radeon HD6670). I mentioned the PC was reluctant to boot first time, so he replaced the whole graphics card. However, the PC is still intermittently reluctant to boot first time (3 tries a few days ago, but OK since).
Before I call Dell again, I want to be sure it's actually their problem and not a Ubuntu/Linux thing! I'm not fluent in Linux, but has anyone got any thoughts on this?
I have an EEEPC 1000HE that has an AzureWave AW-NE766 wireless card. As far as I know, the card is based on the Ralink 2860 chipset.
It always worked fine under eeebuntu 3.0, but I just installed Ubuntu NBR 10.4 and now it's not detected at all.
Kernel : 2.6.32-22-generic i686
lspci and lshw show no mention of wireless card at all. Network-manager and wicd both show wired connections, but no mention of wireless at all.
I followed the instructions on the "Solved" post to install the latest Ralink driver from Jan 29. It all went fine, except "ifconfig wlan0 up/down" and "ifconfig ra0 up/down" both return "ERROR while getting interface flags: No such device"
how to tell Ubuntu that I have a wireless card in there?
I just received my Slackware 13.1 & the 'Official Guide to Slackware Linux' book. I know that there is a big learning curve to use Slackware and that is why I purchased it - according to Distrowatch, "...if you learn Slackware, you learn Linux!" But, while I am 'learning Linux', I would still like to have a linux distro installed that would be more of a 'no-brainer'.
So the question is, which distro should I install first, Slackware or say, OpenSuse? I know that if I were going to dual-boot with XP, that XP should be installed first - does order matter for 2 linux distros too? Also, are there any points to remember to do during the installation processes so that I end up with a working, dual-boot computer?
I have a Dell XPS M1330 with Opensuse 11.2 and Windows Vista Business in a dual boot hard disk.
I was using Fedora 11 before Opensuse, and it was fast and performed well. However I installed Opensuse because I like KDE 4.3 and this is the best KDE distro.
After the last kernel update my system lost initrd, I restored creating an initrd with chroot, mount and mkinitrd from a rescue disk. After first boot, I reinstalled the kernel update, so the initrd was replaced by the new one created in the update.
However, my system is very slow, I don't know where to look for bad configuration or anything else. The boot process took 220 seconds.
I'm currently trying to install ubuntu but the installation process hangs on the second page of the installation (right after select language) I am booting from a usb. NO other OS is installed and I'm currently in "try it now" mode.
