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 reference to the containing vm object while page is mapped. which went in after I cvsup'd. Is there a change the crash is due to the above ? Hardware is pretty generic, we have the same configs on a number...

Hi, Running 9.2-PRERELEASE #19 r253313 I got the following panic Fatal trap 12: page fault while in kernel mode cpuid = 22; apic id = 46 fault virtual address = 0xffffff827ebca30c fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff81983055 stack pointer = 0x28:0xffffffcf75bd60a0 frame pointer = 0x28:0xffffffcf75bd68f0

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. The system panicked again overn...

Occasionally stopping amd freezes my system. It's a rare occurrence, and I haven't found a reliable way to reproduce it. It's also a real freeze, so there's no way to get into the debugger or grab a core dump. I only can perform the 4 seconds hard shutdown to revive the system. I run amd through sysutils/automounter, which is a scripting solution that generates an amd.map file
