I beleive that int_status = c67x00_ll_hpi_status(c67x00); if (!int_status) return IRQ_NONE; is always exiting IRQ_NONE; If I replace the request_irq() call with installation of a timer service routine that basically periodically calls the interrupt handler, everything works fine - albeit slowly. -- Dave Lynch DLA Systems Software Development: Embedded Linux 717.627.3770 [EMAIL PROTECTED] http://www.dlasys.net fax: 1.253.369.9244 Cell: 1.717.587.7774 Over 25 years' experience in platforms, languages, and technologies too numerous to list.
