Hello,
I encounter the following problem with FreeBSD 3.1 on a ThinkPad 770ED:
The machine has 128 MB of RAM. 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:
