Everyhting seems to be working fine but when I try to compile my kernel, the 'make config' 'make dep' and 'make clean' all work fine, but when I do 'make', it proceeds as expected for a while but then gives an error message: Process swapper (pid:0, process nr:0, stackpage=001ae000) . . . kfree of non-kmalloced memory: 001afff8, next=deadbeef, order=0 task [0] (swapper) killed: unable to recover Kernel panic: Trying to free up swapper memory space In swapper task - not syncing After this, the computer locks up and the only things I can do is to shut it down. I am using kernel 1.2.1 which was compiled with my previous motherboard and CPU (486slc2). Should I reinstall linux with a newer kernel (which I planned on doing anyway).

Use the kdebug-1.1.tar.gz package (grep the ls-lR file at your favorite Linux archive for it) on your local machine. This will let you examine variables and invoke kernel functions (but not break points of any form, nor single stepping). You can get the equivalent of breakpoints by adding a semaphore to your code, adding decrements where you want breaks, and incrementing the sempahore with gdb when you want to continue. You can also move your code out into user land (perhaps with stubs in the kernel for interrupt handling) and use regular GDB on it. -- Everyone dies, but not everyone lives. ------------------------------ From: ghharrac@ouray.cudenver.edu (George Harrach) Crossposted-To: comp.os.linux,comp.os.linux.misc Subject: READ ONLY FILE SYSTEM, HELP Date: 30 Sep 1995 10:12:25 GMT :-( For some unknown reason, my system "/" is now seen as read-only and therefore will not boot.

Date: 30 Sep 1995 01:00:02 GMT I am trying to add a little bit of security to my pc, and I could really use a copy of sulogin. If anyone has written this utility, please let me know. For those of you who don't know what sulogin is, it basically asks for a root password, and gives the user a shell on successful password entry. On failure, it can either give a non-zero exit status, or loop forever asking for a password. It's basically used when your system is coming up, and the fsck fails to the extent that the disk must be repaired interactively - the problem is that we currently just hand over a root shell to anyone who's smart enough to trash the disk or request single user mode(not a real good thing in my opinion).
