Running a script called thumbnails, which uses imagemagick's convert
utility, I got this on a mainline 2.6.16.38:

More from the same machine -- it really doesn't like the script, which
simply does:
nice -n 19 transcode -q 0 -o $FIL.img/$FIL.img -y im -F png -x
ffmpeg,null -i $FIL.avi -c \

nice -n 19 convert -thumbnail 80x60 $IMG.png $THUMBS/$IMG.jpg
nice -n 19 montage -tile 15 -geometry +1,+1 $FIL.img/$THUMBS/*.jpg $FIL.jpg
I run the same script on another machine without drama.
Any suggestions? Please cc: me.

Two things:
a. Can you try a recent/current kernel to see if this happens?
b. The "Tainted: GF" means that a module was forcibly loaded.
What module was this? and is it compatible with a 2.6.16.38 kernel?
Can you reproduce this problem without having that module loaded?

Randy, thanks for responding. I discovered that the files the script was
operating on were corrupt, so let me see if it recurs with healthy files.
It's the lirc module that generates the GF flag --
lirc_serial: no version for "lirc_unregister_plugin" found: kernel
tainted.
So it's not actually forced. I'll remove it if this problem recurs.
I've tried 2.6.18 and 2.6.19 on this box, and they are moderately stable
if I use acpi_use_timer_override. It's a production machine, so I can't
experiment much.

Which will make it awkward for my suggestion.. The box I was seeing
this on turned out to have hardware problems. A run of memtest86 may
show up something. Then again, maybe it won't. The failing box
I had ran memtest86 for days without incident, despite that the
capacitors on the motherboard were oozing out their goo.

Hi Dave,
Don't just remove the lirc module(s). They need to have never been
loaded at all.
