However, if I let FreeBSD determine the amount of RAM or set MAXMEM=128*1024, the machine freezes on every reboot attempt. Occasionally it also freezes during normal operation. Freezing means that even the (so-called) power switch does not work and I have to press the reset button with the help of a ballpen. One solution of the problem is to set the amount of RAM to 96 MB in the kernel configuration file. In that case none of the problems shows up. However I would prefer using the full memory as well as understanding the problem. Is this a known problem? Is it a ThinkPad specific problem? Might there be a memory defect? Opinions, solutions and suggestions are appreciated. TIA Ralf P.S.: The dmesg output of the machine is as follows: Copyright (c) 1992-1999 FreeBSD Inc.
