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

Hello! My attempt to build openoffice.org-3 seems to be hanging. Pressing Ctrl-T produces: load: 0.11 cmd: tcsh 79759 [sleeping without queue] 0.00u 0.00s 0% 0k (tcsh is used by OOo's build-script). What is this "sleeping without queue" state, and why is process in it for so long? This is an 4-CPU amd64 system with 4Gb of RAM. Only 16% of the swap is currently in use and

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

Many published analyses which build on post-dominance assume a canonical single-dominator-tree form induced by unifying all exits (and often adding a virtual edge from START to END). In contrast, it seems that the current LLVM post-dominator analysis only operates in a mode in which it generates a forest of post-dominator trees, with one rooted at each exit node. The problem this can cause is

Hi. I?m trying to use the speex library in c#, everything seems to works right, when I call the speex_encode_int function it always return 0, any help would be appreciated. Here?s the sequence of calls: //Initialization _Mode = speex_lib_get_mode(0); _State = speex_encoder_init(_Mode); fixed (int* __FrameSize = &_FrameSize, __Complexity =

I'm running 9.2-RC4 on a handful of desktop and server machines (both i386 and amd64). I have seen three panics (all vm_page_unwire) on one of those systems only (amd64 server) during the past week. The first two panics were triggered when shutting down the ntpd daemon (a recent development snapshot version of ntpd: 4.2.7p387). Exiting a later release (p388) has not triggered the panic.

Hi Tim, My mistake not including the llvm-dev, excuse me. affinityElement.__bits[0] worked fine for me, thank you. I am new in using the API for Constants and I am facing the error "incomplete type is not allowed" on the last last of below code: Type * ET = IntegerType::getInt64Ty(I.getContext()); unsigned long size = cpuAffinityVector.size(); ArrayType * AT = ArrayType::get(ET,size);

Could people who are experiencing boot-time hangs in 4.9-PRERELEASE try the following patch to see if it helps? I've had one positive report so far, but it would be helpful to get more feedback to determine if this is the right fix to be committed. The problem was that interrupts were getting unmasked too early in the boot process, causing an interrupt storm that usually occurred while USB

Hi John, First, I have not much experience dealing with complex dial plans. But since you asked, thought of some feedback. In my opinion .conf files should be kept as simple as possible. It should provide straight forward and simple manipulations to simple & common applications. If more complex manipulations are necessary, then those scenarios could be built using scripts. Therefore, I think

Hello, There it is, all my computers on FreeBSD 9.1-RELEASE had panic. I can just say there is a problem in the 9.1-RELEASE because I had no panic before. What afraid me is that my production server also panic'ed a few days ago, fortunately it does not appears so often. This is a panic that happened on my desktop computer, with a graphic card. The crash usually appears when X starts. GNU

This week has been very productive and has shown a huge leap forward in Asterisk development. The creation of the new concepts of an "unstable" branch of the code will, I believe, make for a better development environment in the long run. With that in mind, I'm going to do something I only infrequently do, which is to re-post something in it's entirety and look for comments

There is a rather serious race with copyout() and process termination in -stable. sysctl_kern_proc() loops through the allproc list writing the results to user memory. If it stalls during the copyout (e.g. the user memory has to take a vm_fault) and the process is ripped out from under it it will go looping into never never land. The solution is very simple, simply

Hello, I see a reproducable panic when doing ibping and aborting it with ^C. My setup is two machines with Mellanox Infinihost III HCAs (one Linux one FreeBSD) connected back-to-back. Details below. I can upload 2 crash dumps, if this is useful. For some reason the port doesn't become ACTIVE, so no packets arrive, but that is probably unrelated. % uname -a FreeBSD cosel.inf.tu-dresden.de

I'll describe the situation. On the server there is a directory /home/user shared as //server/user$, and symbolic link to /tmp in it. If I access it via smbclient, I can browse into //server/user$/tmp and access /tmp on server. Also I can manage file permissions through samba unix extensions. But if I mount it as cifs filesystem, samba does not dereference symlink, and I can not access remote

Hi Nadav, On 14/11/13 17:38, Nadav Rotem wrote: > Sure. Vectorization of stores is done by loading the current value from memory, blending the new value and saving it back to memory. Just a side note: You may run into trouble with this approach when people start using the loop vectorizer in combination with multi threading. The load/blend/store scheme introduces a race condition in this

Nadav and Arnold, What is the current status of vectorization pragmas? Do you think that's something I might be able to take on if you two are busy with other things?
