Not sent to bugs@ because I'm not sure it could do much there.  I'm hoping 
someone may be able to give hints on what to check, so I can resolve this 
small issue.

I have a directory with 8000 .jpg's.  I run ImageMagick over these to cut out
a certain section in order to later make an .avi out of them.  Yet my kernel
freezes up.  Observed in X and in console.  [1]No drop to DDB because the USB
keyboard is disabled from dropping into DDB (I do not have a serial console 
device).  Here is the script:

---
#!/bin/sh

for i in 1*jpg; do 

	convert -resize 1024x768 -extract 1200x1000+300+0 $i AA$i
done

I've not experienced any freezeups on the previous kernel from a month ago,
so it may (or not) be from something that's changed since.  Here is what
I've done to cross-check what the problem may be:

* I checked source trees for anything that went in the last 5 weeks but did not
find anything that may be the culprit at first glance.
* I've booted the kernel with boot -d in order to set break points (mainly wd and ata stuff) because on my USB keyboard I cannot enter into DDB from console.  This is to debug.  It didn't show anything when I stabbed into it.
* I've disabled nviic and other i2c stuff and that wasn't it.  
* I've removed the only hardware card in the system in order to make sure it's not the ahc driver.
* disabling apmd because of changes to hw_setperf code still froze the kernel.

All finger pointings and penetrations into finding the problem have resulted
in a NO-GO and I still get Kernel FREEZE UPS!  (Infinite loops?) see 
reference [1] (can't drop to DDB).  There are no messages in the logs about
any bad hardware.

Why would you wanna do that?!!!  can't you follow the precedure?!!!!



You know.. no matter what you say, you make no sense!  I've been watching
you, loser!  And what I saw was that you restored the kernel and userland
from last month!  Ah yeah!  And you were mumbling to yourself saying the
deraadt(!) doesn't want you to go back (revert).  Yet you broke that rule
as well!  DO YOU NEVER LEARN!?!!!!!

Anyhow!  watching you for a day now.. and your computer hasn't frozen up 
yet meaning perhaps that there is any new code for the last 30 days that
causes the freeze ups!!!

GET A LIFE PETER!  SERIOUSLY!  US SNOOPING DOGS DON'T HAVE TIME TO WATCH
