Hello, First let me thank you (in case I forget :-) for the great work you've accomplished! I have a few comments/questions regarding diskless and kernel debug support in this snapshot. When running a diskless station using nfs shared /usr, /usr needs to be mounted very earlier on in /etc/rc and /etc/netstart. In the current scripts, "mount -a -t nfs" is started after system daemons which require /usr to be mounted, and therefore the system fails to start. The mount command may need to be moved into middle of /etc/netstart where network has been set up but before starting any network daemons. 2) My 'diskless' station has only a DOS partition and no FreeBSD partition in a wd0 (ST506). It panics during diskless boot. I traced down the panic to wdopen which was getting an integer division fault. The trace is as follows: configure() swapconf() wdsize() wdopen() ---idiv fault Is this a known problem? I got around the problem by bypassing wdopen() but wasn't able to trace further down because no symbols were loaded into the kernel, and ddb trace shows no names. I modified netboot to load symbol table over the net but it seems to have no effect. What other things do I need to do to get the symbol table loaded into ddb? Thank you again! -chain -- Chain Lee Tandem Computers, Inc. Voice: (512) 432-8969 14231 Tandem Boulevard Email: chain@isd.tandem.com Austin, TX 78728-6699 Office: 2359
