But after playing around with different versions and patches, and actually running the same kernel for a day or more I ran into severe problems. The problem can be triggered by a number of things, ususally involving semi-heavy disk activitity (kernel recompile, apt-get installs...). It seems to only happen after the system has been up for a while (10+ hours). Suddenly the CPU usage jumps to 100%, and the load avarage to 10 or more. The system becomes completely unresponsive, even the mouse pointer freezes for long periods of time. It looks like most of the CPU time is spent in kswapd, and some in kupdated. The harddisk LED shows almost no activity. I haven't verified (yet) that this is -acX only, but vanilla 2.4.9 did not have this problem. System is a Duron on KT133 chipset, 256M RAM, 300M swap, reiserfs. /cyr ----------------------------------------------------------------------- Cat: Come on bud, you're not doing anything I wouldn't do.
