Unfortunately, I cannot get past the compile of the new kernel, since the existing kernel (i.e., the one from the distribution) keeps panicing. Here is what I get on the screen (somewhat abridged): Fatal trap 1: privileged instruction fault while in kernel mode instruction pointer = 0x8:0xf013d400 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = Idle interrupt mask = panic: privileged instruction fault syncing disks Fatal trap 12, ... etc etc My system has an Asus PCI/I-486SP3G motherboard with and integrated NCR SCSI 2 controller and a 100 MHz Intel 486DX4, 256 kB L2 cache, and 16 Mb DRAM. I have set the cache to do write-through instead of the defalt copy-back. (In the BIOS that is, maybe the kernel overrides this.) The only hard drive is a 500Mb SCSI 2 device. I am uncertain what a useful kernel bug report looks like, so I have probably left out the important stuff and included stuff you don't care about. If that is indeed th case, please ask me for the relevant information. I tried installing FreeBSD 1.1.5.1, but it could not read the sd0 device during installation. (1.1.5.1 works great on my laptop with its IDE hard drive.) I need to have some Unix variant (i.e., FreeBSD, NetBSD, or Linux) on this system within about a week (after that this system is going to fly to a friend of mine Europe...), and if you can help me to get FreeBSD to work, that would be the solution I prefer.
