On my VIA box, the machine locks up solid= =20 within a short period of time after starting the daemon. If I already have= =20 a session open, the machine is somewhat responsive, but if it needs to load= =20 anything off disk (I am guessing here), I am hosed. I just need to do a=20 few "apcacess status" calls, and then sysctl -A and the box will hang. I=20 have the machine hooked up via serial console. Is there any debugging info= =20 that would be helpful to find out where the problem is ? (ps, trace and=20 dump below). Should I open a PR ? This is with RELENG_5. sysctl -A and then the last line is below that it shows and hangs on. ... dev.orm.0.%parent: isa0 dev.sc.0.%desc: System console dev.sc.0.%driver: sc dev.sc.0.%parent: isa0 dev.vga.0.%desc: Generic ISA VGA dev.vga.0.%driver: vga dev.vga.0.%parent: isa0 dev.ugen.0.%desc: American Power Conversion Back-UPS RS 1500 FW:8.g8 .D USB= =20 FW:g8, rev 1.10/1.06, addr 2 dev.ugen.0.%driver: ugen dev.ugen.0.%location: port=3D0 In a non hanging state, it will also print out the following 2 lines after= =20 the port=3D0 line dev.ugen.0.%pnpinfo: vendor=3D0x051d product=3D0x0002 devclass=3D0x00=20 devsubclass=3D0x00 sernum=3D"JB0439029117 " dev.ugen.0.%parent: uhub1 [via-4port]# dmesg Copyright (c) 1992-2005 The FreeBSD Project.
