Hi all! I'm having problems no end on my 4.8-STABLE box, and I hope you can help me. My processes get lots of signals (mostly 6, 10 and 11), and my kernel dumps core very often. I have the core dumps from the 4 latest crashes. See attachment for more info. Notice the common values for IdlePTD and initial pcb. Does this mean anything? There are other problems as well: 1) Some time ago KDE

Hi all, Virtual ISAs such as WebAssembly and NVPTX use infinite virtual register sets instead of traditional phsyical registers. PrologEpilogInserter is run after register allocation and asserts that all virtuals have been allocated but doesn't otherwise depend on this if scavenging is not needed. We'd like to use the target-independent PEI code for WebAssembly, so we're proposing a

Hello, I have been studying LLVM and started to create a new backend for a new RISC architecture. Now I need some help to get forward with my project. I'm quite new to compiling techniques so I'm sorry for the stupid questions. Question 1: My idea is to lower the select SDNode as follows: %res1 = %falseVal %res2 = setc %trueVal, %condition Where setc is conditional mov. The

Hi, My machine just bombed when I did the following stupid command. :(){:|:};: Zsh chewed up everything on the machine... I ran it knowing I'd probably have to reboot. But, I hardly expected it to panic. Or, was that normal? Anyway, the following is some detail... Please mail me if there is more I'm ment to do. Thanks in advance :) ultraviolet@tulip:~ %> uname -a FreeBSD

Some more crashes of 4.8-RELEASE. Lets see what do I have today: # ls -l /var/crash total 1576676 -rw-r--r-- 1 root wheel 2 Jul 30 13:31 bounds -rw-r--r-- 1 root wheel 2193252 Jun 25 17:30 kernel.0 -rw-r--r-- 1 root wheel 2193252 Jul 4 00:08 kernel.1 -rw-r--r-- 1 root wheel 2193252 Jul 15 19:28 kernel.2 -rw-r--r-- 1 root wheel 2193252 Jul 16 17:50 kernel.3

And then I should be ready to roll with my project.. I have some fine tuning of the looks to do after, but funtionality first! This is probably a rails question.. but I''m not sure where to sign up for the rails questions email group? (I guess I turned this into a 2 question email). I''ll ask here and then if someone will send me the url of where I go to sign up for the rails

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

I have raised this issue a couple of times and had no response. I am hoping that in the last few months someone else may have had the same scenario and have had more success in resolving the issue than I am. I have 3 domUs running 2.6.21.7-5.fc8xen, running on a 32 bit host running 2.6.21-7.fc7xen (xen-3.1.2-2.fc7) I have had a number of occerances where the bridge stops forwarding packets

Dear collagues, could someone sched me a light about the following crash (I'm almost sure about hardware, temperature, etc...) Machine is fairly stable; however, there are occational crashes, similar to this one; backtraces are almost always single-step. It's 4.8-R, dmesg and gdb -k output follows ====================================================================================

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

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,

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

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

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.

The following 5 patches are re-submissions of the vt-d patch. This set of patches has been tested against cs# 15080 and is now much more mature and tested against more environments than the original patch. Specifically, we have successfully tested the patch with following environements: - 32/64-bit Linux HVM guest - 32-bit Windows XP/Vista (64-bit should work but did not test) -
