Hi All, I finally finished downloading the latest SNAP and started to install it. First I made the install disks using dd. Then I booted the floppies and did a "normal" install. About the only things to note are: two SCSI disks (entire disk is used), the primary disk uses all partitions (a,e,f, g,h) for filesystems plus b for swap. I then had a devil of a time booting from the main system disk (recently running 2.0R). I needed to rewrite the boot block a bunch of times before it finally "took". When it failed the system was just booting (the primary booter is loading /kernel). The first 3 of the spining bars printed and then nothing. In any case, I got around this and the system started to boot. At this point the system is probed and promptly crashes with a fatal trap 12. I rebooted and select -c to look at what it was probing. This is were things started to get weird. It turns out that there are four entries marked enabled but has device names of zero/one as follows: Device Port irq drq iomem iosize unit flags enabled fdc0 0x3f0 6 2 0x0 0 0 0x0 Yes . . . aha0 0x330 -1 5 0x0 0 0 0x0 Yes aic0 0x340 11 -1 0x0 0 0 0x0 Yes 0 0x1f88 10 -1 0x0 0 0 0x0 Yes 1 0x350 5 -1 0x0 0 1 0x0 Yes sea0 0x0 5 -1 0xc8000 8192 0 0x0 Yes . . . ze0 0x300 10 -1 0xd8000 0 0 0x0 Yes zp0 0x300 10 -1 0xd8000 0 0 0x0 Yes 0 0xffffffff -1 -1 0x0 0 0 0x0 Yes 0 0xf0 13 -1 0x0 0 0 0x0 Yes I've edited some of the less than important stuff. The problem started immediately after the probe of aic0. The system got the fatal trap 12 and halted. I did a "disable 0" & "disable 1" and the system would now continue to just after the probe of zp0 when it then traped out again. The problem is I can't disable these additional "0" devices since the assumption of the code is a device name is unique. Any suggestions? In case anyone is curious, here is the trap. I suspect you won't need it... but better safe than sorry. This is with all devices enabled: st0(aha0:6:0): Sequential-Access density code 0x8c, drive empty aic0 not found at 0x340 Fatal Trap 12: page fault while in kernel mode fault virtual address = 0x431f4a30 fault code = supervisor read, page not present instruction pointer = 0x8:0xf01c69a4 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 () interrupt mask = net tty bio panic: page fault The system is an AMD DX2/80, 16MB, VLB/ISA Adaptec 1542B, 1GB SCSI-2 (DEC), Archive Python Tape SMC Elite16T This configuration worked fine under 1.1.5.1 & 2.0R. Thanks for any help anyone can offer! - Jeff
