   I had just about enough time before running out the door to work this
morning to try a couple of things. Here is what I've done so far.

I had the dfly-stable-20041009.iso.gz file on hand so I went ahead and
installed it instead of the dfly-20041107-stable.iso.gz. Unable to repeat
the keyboard loss (non-debug kernel).

I had downloaded the two following kernels:


When I boot from either of these, the problem is easily reproduced.

DragonFly workstation.zip 1.1-CURRENT DragonFly 1.1-CURRENT #0: Sat Oct  2
00:19:37 GMT 2004    
root@xxxxxxxxxxxxxxxxxxxxxx:/usr/obj/usr/src/sys/GENERIC  i386

20041009 (non-debug):
DragonFly workstation.zip 1.1-CURRENT DragonFly 1.1-CURRENT #0: Sat Oct  9
01:47:25 PDT 2004    
dillon@xxxxxxxxxxxxxxxxxxxxx:/usr/obj/usr/src/sys/GENERIC  i386

DragonFly workstation.zip 1.1-CURRENT DragonFly 1.1-CURRENT #0: Thu Oct 21
00:17:13 GMT 2004    
root@xxxxxxxxxxxxxxxxxxxxxx:/usr/obj/usr/src/sys/GENERIC  i386

The two 2CSNAP kernels are debug kernels and the 20041009 is not. Maybe the
problem manifests with a debug kernel only. At this stage I can either put
the 20041107 iso build back on, cvsup and try building a non-debug kernel
or look for a repository of non-debug kernels. This morning my time was
limited so I only looked at:


If there is a non-debug kernel repository where I could get a non-debug
version of the 20041107 kernel it would be quicker than downloading all the
source from cvs, as at present I currently have no source code and I'd have
to do so by controlling the box from remote (telnet/ssh). 

If I am unable to reproduce with a newer non-debug it might focus attention
on what is different in the debug kernels that is causing the problem.
