Segmentation fault + error on bootup

xushi · 12-30-2004, 04:52 AM

EDIT Pinpointed the problem.. The explanation starts at post #8

I've been having alot of trouble with slack 10.1 lately on my laptop (presario x1000). I witnessed some file system corruption when i recompiled a kernel, but that's so far solved.

Now (with a clean install of kernel 2.4.28 from slack's site), when i boot up, i get a Segmentation fault. Its too fast to read, but i think it comes right after agpgart.

Also, if i login, and type dmesg, i cant see what happened in booting, all i see is pages and pages of this

The only weird thing i see now is that i get these ... 'signal errors' (signal 2) with Mplayer whenever i move any folder, surf the web, etc.. while watching an avi or dvd...

Any help appreciated.
Thanks

I would try to disable hotplug and load the needed modules in /etc/rc.d/rc.modules as you use a 2.4
kernel, see if it fixes the problem...

xushi · 12-30-2004, 09:09 AM

Hello again Cedrik

You sure do hate hotplug. =). Btw this problem comes before hotplug is being loaded. I've recompiled the kernel, and got rid of PCI Express, so that's gone. But i still have a
hw_random: RNG not detected
i810_rng: RNG not detected

errors as you can see. I'ts probably the usb mouse (which it detects, but is not working atm). As for data corruption, ill keep an eye out for that today and see if it happens again or not.

Also, slight off topic, When i recompile the kernel, is it safe to use 'checkinstall' instead of 'make install' ? If not, is it safe to remove kernel-ide-2.4.28 from pkgtool, since i recompile anyway?

Bah, as i finished this post, the laptop froze on me, and the caps lock kept flashing...

This is not turning out well =/ Is there anyway i can find out what's going on?

Hey I find hotplug not bad

but in your first post I saw many lines with "hotplug" keyword
so I tought it won't hurt to give a try to disable it.

Did you compile hw_random as module ? If yes, what happen when you rmmod, then
modprobe it ?

For your last post, what was your last action and what programs were running in your comp ?

I don't think i did, i didn't see it in the kernel setup when i was modifying a few things.. And its not loaded, if i do try to modprobe it i get

Code:

root@xushitop:~# modprobe hw_random
/lib/modules/2.4.28/kernel/drivers/char/hw_random.o: init_module: No such device
/lib/modules/2.4.28/kernel/drivers/char/hw_random.o: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
      You may find more information in syslog or the output fromdmesg
/lib/modules/2.4.28/kernel/drivers/char/hw_random.o: insmod /lib/modules/2.4.28/kernel/drivers/char/hw_random.o failed
/lib/modules/2.4.28/kernel/drivers/char/hw_random.o: insmod hw_random failed

Is it important?

The usual KDE, xmms, xchat, but it happened when i tried loading Azureus. Laptop froze, and caps lock kept flashing. When i rebooted, i tried running it again, but it refused, untill i tried through the console. Afterwards i ran dmesg and got the message above.

EDIT:

Here's another one just now... while im using mplayer. I think all this might have to do with hw_random.

If you're using hotplug, you could try to add hw_random to /etc/hotplug/blacklist as your
hardware does not seem have a random generator (I guess that from your output of
modprobe hw_random).

xushi · 01-02-2005, 04:39 AM

Still need help =/ I'm not sure if i should start a new thread or not, so ill just continue here..

I've managed to get rid of almost all the problems but two... I added the following to the blacklist, and dmesg is much cleaner now. I'd opt them out with a kernel recompile, but... see below.. =/
snd-intel8x0m
fglrx (drivers kept hanging)
hw_random
pciehp
pci_hotplug
shpchp
i810_rng
scsi_hostadapter

But..

I still am getting one Segmentation fault in bootup, and its from agpgart.

Code:

Sometimes it goes through, but says can't modprobe agpgart due to some error (i'll post it when i see it again).

The second problem i guess i'll solve later with a new thread.. Its got to do with the fact that my laptop totally fails on me whenever i recompile the kernel (2.4.28).. All i want to do is enable highmem (1Gig), and all i get when i recompile the kernel are segmentation faults, kernel panicks, laptop hangs, data corruption, etc... (like the random firefox, mplayer seg faults above) Leading me to revert back to the default ide kernel from slack/pb. I'm going to try not modifying anything, and just do a recompile, and see if it still happens.

But let me solve one problem at a time =)
Thanks.

You could try a memory test :
http://freshmeat.net/projects/memtest86/

Download and burn the iso image and boot from the CD, it will test your memory

Another thing to test is play with your bios values for AGP (disable fastwrite, etc...) you can put
agpart in hotplug too or boot with kernel parameter option : "noagp" or append="noagp" in a
lilo.conf

Thanks. I let it run for a few hours.. It did the tests 5 times over, and thankfully there were no errors. My memory is alright.

The laptop's BIOS is simple.. no AGP settings there. However, if i put agpgart in the blacklist, wont that prevent X from loading up?

As for the problem.. I've almost pinpointed it. Everytime i recompiled the kernel, i changed three things..
Toshiba Laptop support (n)
Dell Laptop Support (n)
High Memory Support (4Gb)
The first two, because my laptop is a Compaq (HP) Presario X1000, and the third because i have 1Gb ram. But this time, i haven't changed anything, just did a recompile, and so far everything still works fine. So i guess my problems are coming from one of these three, most probably the High mem support...

I could just enable that to make sure, but it will take time to recompile, and i don't want to risk any data corruption again.. I'm just confused to why the problems are happening, especially when i have 1Gig of ram..
