Yep, and the same thing happens.... Someone else compiled a kernel with the same config on their machine but when I got it, it always panics and reboots since it can't mount the root partition. > - Do you use any LKM's ? > (A make world might fail to rebuild a LKM, and > the incompatible LKM from an earlier build might > be left alone in /lkm.) Hmmm, I never rmed any of the old /lkm's but what I did was to be sure since David told me about it, I just cd /usr/src/lkm and then did a make clean, make all, and then make install. > - Can you boot single user (enter "-s" at the "Boot: " > prompt, fsck the file systems and mount (r/o) your > /var partition ? Hmmm, this is one thing I haven't tried yet.... For some reason, the original -current kernel of 12/28/95 seemed to have messed up the root partition and deleted the entire /bin directory as well as the /stand directory, newer kernels seems to have deleted my /mnt directory but the latest ones just panic with the vm_fault and doesn't mess up my partition. I'm still on the 11/23/95 kernel now on a 1/4/96 -current system so I'm not sure what really is the problem since it seems like it's something with the memory but it worked fine with everything up to 11/23/95.
