The output of ksymoops, and some other miscellaneous information is attached, as I promised. The box is an AMD K6-300, with 64Mb memory, and around 130Mb swap (from which ~110Mb was free, there was no VM pressure). It is running Debian unstable. What I did was to boot into my system as usual, then stop all processes I didn't need. After that, I did a `touch /tmp/foo', then a `sync'. /tmp is /var/cache/ext3test, despite the filename, it is ext2, mounted from an ext3 partition (/) (see the output of mount below). `sync' hung, and the load started to slowly increase, shortly before I rebooted, it was almost at 3: 12:02:26 up 6 min, 2 users, load average: 2.97, 1.81, 0.78 (btw, before doing the `sync', the load was 0.99; with 2.4.14, my usual load is between 0.20-0.50) ,----[ mount ] | /dev/hda3 on / type ext3 (rw) | proc on /proc type proc (rw) | /dev/hda1 on /boot type ext2 (rw) | /dev/hdd2 on /gnu type ext2 (rw) | /dev/hdd1 on /gnu/mnt type ext2 (rw) | /dev/hda6 on /gnu/work type ext3 (rw) | /usr/bin/emacs on /bin/emacs type none (rw,bind) | /gnu/work/cache-apt/archives on /var/cache/apt/archives type none (rw,bind) | /gnu/work/lib-apt/lists on /var/lib/apt/lists type none (rw,bind) | /gnu/work/cache-apt/archives on /chroot/base/var/cache/apt/archives type none (rw,bind) | /gnu/work/lib-apt/lists on /chroot/base/var/lib/apt/lists type none (rw,bind) | /var/cache/ext3test on /chroot/base/tmp type ext2 (rw,loop=/dev/loop0) | devfs on /chroot/base/dev type devfs (rw) | proc on /chroot/base/proc type proc (rw) `----
