similar to: kern/53717: 4.8-RELEASE kernel panic (page fault)

Every few days now I get a panic like the one shown in the attached backtrace. I've made sure my filesystem is clean with fsck and even turned off write caching on my IDE drive. Maybe someone here can figure out what is wrong. Let me know if you need more information.

Hi stable, nice you see you again. I was one of those guys who was seeing constand panics on 24 hour boundaries but couldn't provide a backtrace due to the ar device not taking a dump. I installed a dedicated drive just to take the dump, and then didn't have a panic for a couple weeks. Now, I am back with, and I have traces to share. The first two, from 2003-09-27 and 2003-09-28

Hello list, I have been fighting this problem for a few days now. I have changed memory and opened the case and monitored for heat. I have been getting the same panic about every 12 to 24 hours. I can let the system sit idle, or run it under a heavy load (cpu and disk), but the panics dont seem to be related to system load. It looks to me like a dangling pointer in softdep_update_inodeblock,

Getting the following panic on a new Dell Poweredge 1650. This machine is going to be a VPN server and has a large number of pptp links configured. The machine is stable if mpd is not running.

Hi, I need some help to understand a backtrace. The situation is as follows: A diskless system acting as a kind of bandwithshaping firewall with both ipfw2 and ipfilter active at the same time. Ipfilter is used for port adress translation. The system panics about once every 6 hours. The network load is very low, only one Windows XP machine is connected but not actively used. I added a disk

Did cvsup on a machine that does just mail processing (well, a lot of spam scanning) and it crashed not too much later. This kernel does not include MFC src/sys/kern/sys_process.c revisions 1.111 and 1.112: Use kmem_alloc_nofault() rather than kmem_alloc_pageable() in procfs_rwmem(). Use vm_page_hold() in place of vm_page_wire() since the page can be freed. Don't hold extra

All: I cvsup'ed earlier this evening and am still able to reproduce this panic at will. Command line, panic backtrace, dmesg, ldd output, and mplayer version follow. If more information is needed, just let me know. % mplayer foo.mov [a quicktime file] [plays for awhile, and then panics] # gdb -k -s /usr/obj/usr/src/sys/LICHEN/kernel.debug -e /var/crash/kernel.2 -c /var/crash/vmcore.2

After about a day and a half or so of uptime, I'm getting the aforementioned panic on the server ... better then having it hang solid, but right now I'm not sure if this is replacing it, or just one being triggered earlier then the other ... First scan through Google, I came across some posts talking about NMBCLUSTERS ... since its at the same settings as my other server (the default)

After some dialog with Terry Lambert on -hackers, I've been advised to post this here. I have a 4.7-RELEASE-p10 box that is suffering regular kernel panics. The machine is a Dell 2650 running primarily as a file/print server to a number of computer labs of about 400 machines (although it also functions as a rembo image server and squid proxy). It mainly stores applications, which

Hello. I'm having a 4.7Rp9 server which is since months quite unstable, so I've compiled a debug kernel and got a crash dump. I'm a programmer and I know a little how to use gdb, I'm not so expert about FreeBSD kernel insides however, so I can't get much from it. Any kind of help is appreciated. This is the crash message: IdlePTD at phsyical address 0x0032f000 initial pcb

Today my system coredumped (4.8-STABLE from Saturday), I believe it's somehow X11 related: X11 crashed first (signal 11). I was running it as root (I know I shouldn't). I didn't think about it and restarted X11. While it was starting, I had a look at the console, there was a bright white message: issignal. This shows up at X11 startup. Then the system coredumped. Below is more

While I was tying down a supernet to the discard interface, the box crashed on me. Its a STABLE box from June 4th. I was in zebra at the time and thought I would route a /24 to ds0 instead of to the IP on ds0 (which I had done for a number of other aggregate routes). The only other "strange" thing about the box is that ds0 is loaded via kld. I will see if I can reproduce it on a

My wife got the following from a system running (effectively) 4.8-RELEASE (I built/installed world just before the kernel version was updated from 4.8-RC to 4.8-RELEASE). I gather she made a few attempts to get mozilla to start and then the system panic'd. According to the crashdump, p->p_leader is NULL but according to the code, this can never happen. This is a UP Athlon XP-1800 with

Hi Ian and others, umount(8) -f does crash here on several just updated 4.8STABLE boxes for nfs volumes. Server is an IRIX server. All clients are FreeBSD. Here is a backtrace: #0 dumpsys () at /usr/src/sys/kern/kern_shutdown.c:487 #1 0xc021f1c0 in boot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:316 #2 0xc021f60d in panic (fmt=0xc03bd664 "from debugger") at

Yesterday I begin a couple of update to the latest 4.8-STABLE. After that the two boxes continues to go in panics as soon as Apache (1.3 from the ports, also freshly recompiled, 2.0.x seems NOT to hang) starts. I don't know if it is related to the other thread : "Kernel core dump in recent 4.8-STABLE" but it is easily reproducible by cvsupping to a today -STABLE and then running

Hi, all-- I've got a 1997 Dell XPS D300 which has been rock-solid over the years, which I'd just upgraded via a PowerLeap iP3/T-1400C. The system seemed stable for several days, so I cvsup'ed and updated this machine from 4.7p10 to 4.8-STABLE, only to get a panic a few hours later. Can anyone make an educated guess as to whether the panic below is related to this upgrade, or

Hello, I'm running 6.4-PRELEASE, last built on 2008-10-05 with /usr/src updated on the same day. I had a panic that looks to me very similiar to the one described here (hence the subject): http://lists.freebsd.org/pipermail/freebsd-stable/2008-September/045405.html What caught my curiosity is the message: Unread portion of the kernel message buffer: acd0: WARNING - TEST_UNIT_READY read

[ Asked on -questions on Friday; re-asking now on -stable without cross-post] I recently upgraded a 4.11-REL machine to 6.0-REL and have run into some snags. While the installation from CD went fine, after configuring and enabling my ed0 NIC, bad things start to happen. FWIW, this machine is an ancient (hardware circa 1991, BIOS circa 1994) dual-Pentium 133 MHz machine, with EISA/PCI and
