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 based on encountered devices and devd events. The SIGHUP it sends to amd to tell it the map file was updated does not cause problems, only a SIGKILL may cause the freeze. Nothing was mounted (by amd) during the last freeze. I don't see any angle to tackle this, but I'm throwing it out here any way, in the hopes that someone actually has an idea how to approach the issue. # uname -a FreeBSD mobileKamikaze.norad 9.2-PRERELEASE FreeBSD 9.2-PRERELEASE #0 r253413: Wed Jul 17 13:12:46 CEST 2013 [email protected]:/usr/obj/HP6510b-91/amd64/usr/src/sys/HP6510b-91 amd64 That's amd's starting message: Jul 22 11:32:28 mobileKamikaze amd[8176]/info: no logfile defined; using stderr Jul 22 11:32:28 mobileKamikaze amd[8176]/info: AM-UTILS VERSION INFORMATION: Jul 22 11:32:28 mobileKamikaze amd[8176]/info: Copyright (c) 1997-2006 Erez Zadok Jul 22 11:32:28 mobileKamikaze amd[8176]/info: Copyright (c) 1990 Jan-Simon Pendry Jul 22 11:32:28 mobileKamikaze amd[8176]/info: Copyright (c) 1990 Imperial College of Science, Technology & Medicine Jul 22 11:32:28 mobileKamikaze amd[8176]/info: Copyright (c) 1990 The Regents of the University of California.
