The kernel is compiling right now, but I cannot reboot this machine until six or seven o'clock
tonight (CET). I will report then.
Well, well, I rebooted the same kernel, now with
MAGIC-SYSRQ enabled. At first the kswapd-effect
wouldn't show up, but now the image is much clearer
than before. kswapd eats constantly 95% cpu time while
the system is "idle".
The System is quite sluggish. Switching between
applications needs ages. After Eclipse has been active
for a few minutes, I it lasts 45 seconds until enough
of Mozilla is swapped back in, and Mozilla has redrawn
its window.
Complete info including SysRq-Meminfo is attached.
