I decided I was going to brave 5.0-CURRENT and give the snapshots available on current.jp.freebsd.org a try. I found a couple issues with installation disks (FWIW, I tried it on the lastest snapshot avail on current.freebsd.org. I got the same results). Anyway, I go through the standard kern/mfsroot floppy deal and when it boots the kernel, everything seems to be going fine until I get the following kernel panic: Fatal trap 12: page fault while in kernel mode fault virtual address = 0xffffffab fault code = supervisor write, page not present instruction pointer = 0x8:0xc0a75ac0 stack pointer = 0x10:0xc6978f68 frame pointer = 0x10:0xc6978f80 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupts enabled, resume, IOPL = 0 current process = 26 (irq10:sn0) trap number = 12 panic: page fault syncing disks... done Uptime: 2s FWIW, it's 5.0-20010804-JPSNAP #0 available off of current.jp.freebsd.org. I noticed it said it was in sn0. So being industrious, I interrupted the autoboot and did: ok set hint.sn.0.disabled=1 Sure enough, that fixed the kernel panic, but here's the next odd piece, my hard drive wasn't showing up! I have a rather standard Adaptec AHA-2940 dmesg reports that ahc0 is there. The lines from the dmesg are (hand typed): ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0x5000-0x50ff mem 0x50000000-0x50000fff irq 15 at device 15.0 on pci0 device_probe_and_attach: ahc0 attach returned 12 errno.h says ENOMEM is 12, so it seems that something in the ahc driver is unable to allocate memory. Dunno where or why, but something is fouling it up. By contrast 4.3-RELEASE doesn't have any issues (I'll try a recent snapshot if that would help). Sorry I can't help out any more, but the debugging tools in the installation disks seem to lacking (understandably). Any help? -gordon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
