panic with today's stable
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...

9.2-RC4 amd64 panic: vm_page_unwire
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...

stopping amd causes a freeze
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
