As an answwer: i am not able to install any linux distribution with a kernel below 2.4.19 :-( The machine freezes in the install process when installing with a kernel of version e.g. 2.4.18 Yes i was in X (KDE) > Please test this again without beeing in X. > > A small stress test can be: > > while true; do dd if=/dev/zero of=/largefile bs=16384 count=131072; done > > this will create a ~ 2gb file in / named largefile. > > You should see an oops/panic output if the LED's are starting again flashing. > The output of above you have to feed ksymoops with. > I've tested this in the following ways: But first my /etc/fstab so you're knowing what i'm talking about ------------snip--------------------- /dev/hda4 / ext2 defaults 1 1 /dev/hda2 /data1 auto noauto,user 0 0 /dev/hda3 /data2 auto noauto,user 0 0 /dev/hdb1 /data3 auto noauto,user 0 0 /dev/hdb2 /data4 auto noauto,user 0 0 /dev/hdb4 /home ext2 defaults 0 2 /dev/hda1 /windows/C vfat users,gid=users,umask=0002,iocharset=iso8859-15,code=437 0 0 /dev/hdb3 swap swap pri=42 0 0 devpts /dev/pts devpts mode=0620,gid=5 0 0 proc /proc proc defaults 0 0 usbdevfs /proc/bus/usb usbdevfs noauto 0 0 /dev/cdrecorder /media/cdrecorder auto ro,noauto,user,exec 0 0 /dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0 /dev/dvd /media/dvd auto ro,noauto,user,exec 0 0 /dev/fd0 /media/floppy auto noauto,user,sync 0 0 ------------snap------------------------------ Before every step i restarted my computer logging into kde as normal user and then switching to a console window, logging in as root. 1. step: I mounted the partitions /data4 and /data1. These are ext3 partitions. Started the suggested command from the console for /data1. After 5 minutes or so i switched to an other consolewindow and started the command in parallel for /data4 nothing unusual happens. After that i make sure that both partitions are mounted as ext3. They were. So i switched to KDE started the DSL connection and Opera. Browsing for 15 Minutes in the internet and nothing unusual happens. 2. step: i have edited /etc/fstab so that / and /home are mounted as ext3, (/ and /home are ext3 partitions.) starting the commands for both partitions. After 20 minutes the system still runs. I decided to conect to the internet. After typing a URL in Opera and pressing <enter> the system freezes. And, it wouldn't start again. After a reboot i landed in the editing mode of grub. So i must restart my system using the installation dvd. This procedure started my recovery system on /data3. After logging in, i was not able to mount /dev/hda4 (/) defect superblock:-( So i do an fsck.ext3 on /dev/hda4 After that i could restart my system. 3. after the desaster from step 3 i tried to log into KDE start DSL and browse. system freezes again but this time without defecting the root-partition. 4. I edited /etc/fstab so that / and /home are ext2 again. Since then all is fine again. What is the conclusion? I do not know. Does anybody else have one.
