Hi -
I see the following when I load a National Instruments DAQ with Analogy:
Analogy: analogy_ni_pcimio: pcimio_attach: found pci-6259 board
analogy_mite 0000:06:04.0: setting latency timer to 64
Analogy: analogy_ni_pcimio: pcimio_attach: found irq 11

Then when I run cat /proc/analogy/00-analogy_ni_pcimio, I get "Killed"
as the only output on the command line and the dmesg shows:
