hi, i hate to follow up my own posts, but i solved my problem and thought i'd share with the list. i only got one response, but someone might find it useful at some point. the problem was that the installer kernel didn't like seeing 4gb of memory. in the bios for the 6450 is a setting: "OS Install Mode". it says that some os' have a tough time installing with > x mb of memory. it limits the available memory to 256mb. as this was the symptom i had, i enabled this bios setting and it installed cleanly. once the system was up, i cvsup'd and rebuilt and installed the world and the kernel. after a few reboots, i disabled the "OS Install Mode" and reenabled all 4gb of memory. the new kernel saw all 4gb of memory with no problems. the machine has been up now for a full day with no signs of crashing. so, my question - why does the install kernel panic? -jon -- Jon Nathan jon@rupture.net http://www.rupture.net/~jon/ ---------- Forwarded message ---------- Date: Tue, 13 Feb 2001 20:07:01 -0500 (EST) From: Jon Nathan <jon@rupture.net> To: freebsd-questions@freebsd.org Subject: panic installing on dell poweredge 6450, 4cpu, 4gb hi, i'm trying to install freebsd 4.2-release on a dell poweredge 6450. it has 4 xeon cpus at 700mhz and 4gb of memory. my process is: boot off kern.flp insert mfsroot.flp wait 10 seconds and i get: Fatal trap 12: pagefault in kernel mode fault virtual address = 0xbff11000 fault code = supervisor write, page not present instruction pointer = 0x8:0xc02d3798 stack pointer = 0x10:0xc0671f34 frame pointer = 0x10:0xc0671f3c 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 = Idle interrupt mask = net tty bio cam trap number = 12 panic: page fault Uptime: 0s if i stop the autoboot of the kernel and do boot -v i get the same fault. prior to that, i get: SMAP type=01 base=00000000 00000220 len = 00000000 00330000 SMAP type=01 base=00000000 00000220 len = 00000000 00330000 SMAP type=01 base=00000000 00000220 len = 00000000 00330000 SMAP type=01 base=00000000 00000220 len = 00000000 00330000 SMAP type=02 base=00000000 00000220 len = 00000000 00330000 SMAP type=02 base=00000000 00000220 len = 00000000 00330000 SMAP type=02 base=00000000 00000220 len = 00000000 00330000 SMAP type=02 base=00000000 00000220 len = 00000000 00330000 i didn't copy all the actual addresses - too tedious. i'm also assuming that there were 4 of the SMAP type=01 because they scrolled off the screen and i couldn't retreive them. i know that 4.2 will run on a 6450 - i have it running on another one. the other one though only has 2 x 550mhz xeons and 1gb of memory. they both have ami megaraid 1600 (dell calls them PERC/2 or soemthing) cards with some disks off them. is it the fact that there are 4 cpus or 4gb of memory? i thought fbsd could handle that. i also made brand new floppies - same result. any ideas? i don't want to have to run linux on this puppy 8-( thanks, -jon -- Jon Nathan jon@rupture.net http://www.rupture.net/~jon/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
