I thought that linux didnīt crash?
 
I thought that linux didnīt crash, but I can consistantly get it to crash just by loading xawtv and moving the xawtv window. I could understand it if just crashed xawtv... but it completly freezes my system and I have to reboot. :(

Any ideas? I would be happy even if there was some way of isolating xawtv so that it doesnīt completely lock up my system.

Huh, linux doesn't crash much -- you must really be pushing your system. Is it too weak to run a memory-intensive X package?

Have you tried to Ctrl-Alt-Backspace out of X?

jimdaworm 09-12-2003 03:19 PM

Umm I donīt think so donīt have the best system but a Celeron 1700 512mb ddr333 ram 40gb 5200 rpm hdd Radeon 9100 128mbddr ....I donīt think it should be a problem???

Is it ctr alt backspace??? Not ctr alt del???

I hope thats not too stupid a question but Linux really seems to crash properly (but ONLY when I load xawtv and move the window)... I think it could be some sort of an IRQ problem but I have no Idea how to sort that sort of thing out :( cant even find my manual that is supposed to tell you which slots share IRQs :(

to kill X it is ctrl+alt+backspace.

depending on your setting ctrl-alt-del may reboot the system. It's unlike windows, in that it is configurable.

Usually killing and restarting X will fix anything, at least for the short time.

And linux doesn't crash, people crash linux.

It does sound like a problem with the display (only after moving the window), so I guess it's just X dying. Have you also tried Ctrl+Atl+F1 to get a login console? Ctrl+Alt+F7 is normally to get back to the X screen if it's working.

I've had to push the reset button probably a dozen times on my red hat 8.0 box in my short history with linux and thru several reinstalls. Sometimes it just locks up and there's no going to a new terminal, no escaping, no ctrl-c'ing, no ctrl-alt-bs, nothing.
Hasn't happened lately tho.

Hmmm, can I use that logic with Windows too? I ask because in all the time I've been using XP (including the beta) it has never once produced a BSOD for me. Must be luck, huh?

ufgeek 09-12-2003 11:46 PM

my only crashes in windows have been either in games: bf1942 or AA, or while writing networking code, usually java.

Redhat 9 I've only been able to crash with hardware failure...dead hard drives don't boot.

I doubt that anyone who has done any programming at all would make a claim like that :)

Operating systems are very complex things, especially when you consider the amount and variety of large, complicated, and potentially flawed software that is running at any given time on a modern PC, which contains any number of complex and potentially uncooperative pieces of hardware. OSes do crash once in a while. Some people use Windows XP for a year with no crashes, some use Linux for a day and have a hard freeze.

If the crash is consistent, there may be a way to localize the problem to keep it from happening. Try running GKrellm or another monitoring application and then seeing if it's possible to duplicate the crash; run 'top' in a terminal window and see if some process is hogging all the CPU right before it freezes. Check the logs, or use tail -f on one of your system logs (/var/log/messages, etc.) to see if anything useful is printed there. Find out if there is a known bug with that software, and see if there's a patch or upgrade that might fix it; use a utility like memtest-86 to test yor RAM and make sure it's okay. There are lots of things to try!

sounds to me like an incompatibility between your tv capture card and your video card. i would try the following(in no particular order)
  • what happens if you switch xawtv to grabdisplay rather than overlay before you move the window?
  • does it work in windows properly?
  • are you using a binary driver for your video card or is it a standard xfree one.
  • do fbtv and streamer run without errors?
  • if you have another machine, after it crashes can you ssh in and see what sort of state the machine is in.

Never locked up on you at all?

jhansman 09-13-2003 12:52 PM

Nope, never. But then, I built my system, installed the OS, took the time to learn it and configure it, don't overclock and maintain things regularly. Have I had apps freeze and need to be terminated? Sure. There's no shortage of crappy software out there written by half-assed programmers. But not BSOD here. Not even from games. Go figure.

MasterC 09-13-2003 12:57 PM

When applications bring down an entire system, that's when I find it time to submit a bug report ;)

I've had my share, they too are few and far between, but even so, I still get them, even with my vast amount of knowledge :rolleyes:

Linux, the kernel, has NEVER brought my system down. It's ALWAYS another application, so yeah, linux (the kernel) never crashes. Not in my experience ;)

Cool

kev82 09-13-2003 12:59 PM

i used win2k for well over a year and it only had one BSOD this was due to the hd motor dying which i think is a perfectly reasonable reason.

<edit> ive had a 2.4 series kernel crash but it was due to proprietry kernel module, other than that i have never seen or heard of a stable kernel crashing.

jhansman 09-13-2003 01:03 PM

Yes, I too am impressed and pleased with how stable Linux is. I just wish it was a tad easier to get things done in. Still, I've managed to install what needs installing, update the updatable, and eventually find the configurators I need. Now I just wish I could connect to our Win2K Exchange server at work without having to buy a 3rd party utility like Crossover. Sigh....
