It looks like motion is running with interrupts off, ignoring the scheduler, or something even more wonky on OMAP3 (gumstix) system

Question

I've just installed linux 2.6.34, ffmpeg 31717 (libs as below) and motion v 8.0.2 and an MT9V032-based sensor. The system is a hacked-together 2.6.34 kernel running on an OMAP3503 motherboard manufactured by Gumstix. The watchdog thread times out, the ccdc driver can't be unloaded, and the system complains that motion is not responding.

I thought I had downloaded/installed motion 3.2.12 but "--version" says "8.0.2"

I think this problem is different than 2009x 07x 05x 075301

Thanks.
