Linux freezes at start up

(1/3) > >>

TheCruelOne:
I recently got a copy of SuSE and i love it.  It is great, but i have one small problem with it, and and other versions of linux.  Sometimes when i boot up the computer linux stops loading and just freezes. It just freezes and at random spots, and doesn't always freeze up.  This doesnt just happen on my computer, it happens on my friends comp too.  The comp with SuSE on it is a Dell inspiron 7500 (yeah i know dell sucks, but i didn't buy it).  Thanks for your help

Calum:
it probably is (as you hint) an issue with trying to detect hardware.

What i suspect is happening is:
the default startup script looks for some hardware, finds one it thinks it can get to work, tries to get it to work, continues trying for a while and eventually gives up and loads the OS (or continues to try). In the meantime user gets very irritated.

The solution (if this is indeed the problem) is read up a bit on how to edit your startup scripts, then using the output of "dmesg", edit your startup scripts to remove the offending entry that makes it look for whatever is causing the delay. alternatively find out how to make whatever item it is work, and do that. this way there won't be a delay when it is trying to make it work on bootup.

if that's not the problem then please ignore this reply.

Faust:
Tried running a copy of Knoppix on that machine?  Knoppix is a "boot of CD" distribution which will help eliminate some errors.

Otherwise:
check if your hardware is supported (red hat / suse sites should help here.)
check for dust
check for heat
how old is your ram?
how old is your hard drive?
are all the connections in your case in snug?

edit:
I meant to say "help eliminate some variables that could be causing errors" rather than "help eliminate errors."

Stryker:
where does it stop? while booting the kernel? while booting services? while booting the gui? if services, what services? what is the message it freezes at?

TheCruelOne:
The laptop is about three years old, and every thing is in working order.  Knoppix works fine on the laptop.  It doesn't stop at just one error message, but it usually stops when it tries to detect the periphials (usb 1394 etc.)  When it freezes, it just freezes and doesn't go any farther in the boot process or give me any error messages, it just freezes.  But what i do not understand is how can it boot fine half of the time without any problems, and the other half of the time it freezes?  And if the start up scripts are the culprit, where can i find out how to edit them?  Thanks.
