NetBSD artworks 1.6.2 NetBSD 1.6.2 (JARTZ) #0: Sun Feb 29 13:44:33 EST 2004     james@artworks:/usr/src/sys/arch/i386/compile/JARTZ i386

About 6 months ago I upgraded my desktop from 1.5 to 1.6.1
and ever since then I have had regular lockups. The result is I 
can't get any sort of response from the machine and have to press the reset
button. There are 2 sure-fire ways of causing this immediately.

1. start an XDMCP client pointed at it's xdm server (e.g. from my WinXP box run
Cygwin/Xfree in XDMCP client mode)

2. access any web page with a CGI behind it hosted on Mr. Crashy's httpd.

It will also periodially lock itself when I've looked at lots of photos
from the web server or played a lot of mp3 over samba etc.

Seems by behaviour to be related to network activity.
Yesterday morning I upgraded to 1.6.2RC4 in vain hope of it going away.
I've just run memtest for nearly 2 hours and found no memory probs.
A few weeks ago I re-compiled a kernel with kernel debugger in
and wasn't able to get it to drop into the debugger after the lockup.

I replaced the ISA NE2000 clone with a NetGear FA311 this afternoon
and all the problems went away (except for a SILO underrun which I'll
ask about elsewhere. So my suspicion is that some housekeeping has
damaged the NE driver since the 1.5* releases.


use the network card :-(
use a different network card :-)
