If you REALLY want to do this, which I wouldn't recommend since it caused instability on my TNT too... But if you do, please apply the included patch and give me the output it has generated. This is my last resort in checking if I possibly did something wrong :( Uncomment this line in src/sys/i386/conf/files.i386: # i386/i386/k6_mem.c standard and reconfig/rebuild your kernel. > > On the other topic - write allocation - should I be seeing an indication > of its status in the boot up messages ?
