Thanks anyway!
Compile what ( the kernel ) ? most probably the compiler is alredy buggy !

do an apt-get update style thingy , if one of the packages to update is a compiler (gcc***) go ahead .

otherwise please give me more infos on your distro and gcc -V etc

Regards

I tried it with 3 different kernels: the Debian Kernel, the Zen Kernel, and the Grml Kernel. The output of "sysctl -a | grep vm. | sort" is from the Debian Kernel. The Zen Kernel sets swappiness to 0, but the Debian sets it to 60, so... and the Grml is similar to the Debian one.

I'd like to try, but don't know how to use other compiler. I'm compiling from Debian sources, so it is just "debuild -k$GPGKEY", and it calls the compiler probably from debian/rules.

If it is a faulty driver, how could I debug it (without freezing again the system and killing it)?

I don't think the problem is in the sources. I have compiled the Debian kernel a few months ago and hadn't noticed anything wrong.

I suspect of some problem in my partitions? Though when I succeeded in compiling the kernel, I had no swap at all (already tried "swapoff -a", and it just started killing many procs...)

Thanks for your help!

yes but its a definition of a bug - otherwise it will be called a nonworking prog Smilie

you compiler worked with sourceX.c but might not with sourY.c
thats why it would be called a bug ...

i am still waiting on your details .

regards

SHELL-QUOTE(1)						User Contributed Perl Documentation					    SHELL-QUOTE(1)

NAME
shell-quote - quote arguments for safe use, unmodified in a shell command SYNOPSIS
shell-quote [switch]... arg... DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands or files with embedded white space or shell globbing characters safely. Here are a few examples. EXAMPLES
ssh preserving args When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and passes them to "$SHELL -c". This doesn't work as intended: ssh host touch 'hi there' # fails It creates 2 files, hi and there. Instead, do this: cmd=`shell-quote touch 'hi there'` ssh host "$cmd" This gives you just 1 file, hi there. process find output It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote: eval set -- `find -type f -print0 | xargs -0 shell-quote --` debug shell scripts shell-quote is better than echo for debugging shell scripts. debug() { [ -z "$debug" ] || shell-quote "debug:" "$@" } With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can. save a command for later shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are things the user can't pass through), you can do something like this: user_switches= while [ $# != 0 ] do case x$1 in x--pass-through) [ $# -gt 1 ] || die "need an argument for $1" user_switches="$user_switches "`shell-quote -- "$2"` shift;; # process other switches esac shift done # later eval "shell-quote some-command $user_switches my args" OPTIONS
--debug Turn debugging on. --help Show the usage message and die. --version Show the version number and exit. AVAILABILITY
