Since then I have been experiencing a freeze of the system consistently after about 10 minutes of uptime. I thought the problem was with the apm driver and disabled it - but the problem remains. I have tried to remove all the drivers I don't need for the basic operations, but the situation has not changed. I also need to disconnect the power source (battery or DC power cord) to reboot at this time since the power switch is also disabled. I suspect the problem has something to do with the ThinkPad's power management that has surfaced only with 3.1 release. I would surely appreciate any help with this problem. >How-To-Repeat: Install 3.1-RELEASE on a ThinkPad 770ED and just reboot the system. You don't even have to login - just let it sit idle for a while; or, you could work on it (make sure you don't work with any crucial files that you cannot recreate) - just wait for long enough for the timer to kick in and freeze the system. >Fix: >Release-Note: >Audit-Trail: State-Changed-From-To: open->analyzed State-Changed-By: nate State-Changed-When: Fri May 28 13:00:51 PDT 1999 State-Changed-Why: When your ThinkPad boots up, note the size of memory reported by the BIOS. Also note the amount of memory reported by FreeBSD at boot. They will be different. FreeBSD needs to be told the amount of memory as reported by your BIOS. Using the 'MAXMEM' option in your kernel configuration file, you should set the memory of your system. On my box, I have the following line in my config file (I have 128MB of memory) options "MAXMEM=130496" # The Thinkpad's reserve some memory Or, you could just guess and do something like: options "MAXMEM=127*1024" if you don't want to figure out. (Salt to how much memory your machine uses).

I set the option "MAXMEM=(191*1024)" as you suggested and BINGO! it seems to solve the problem, atleast in console mode. I will let you know if I encounter any problems while running X.
