The observed behavior suggests that RF_SHAREABLE is not being honored. dpt99: DPT PM2022A/9X FW Rev. 07CK, 1 channel, 64 CCBs dpt0: <DPT PM2x22A/9X> at slot 4 on eisa0 dpt0: DPT PM2022A/9X FW Rev. 07CK, 1 channel, 64 CCBs dpt99: DPT PM2022A/9X FW Rev. 005A, 1 channel, 64 CCBs dpt1: <DPT PM2x22A/9X> at slot 5 on eisa0 dpt1: No irq?! device_probe_and_attach: dpt1 attach returned -1 (The 'dpt99' lines are an artifact of the mechanism I'm using to complete the probe.) Now, since the resource ranges aren't printed anymore, you can't see that both cards are using (set to use) the same IRQ. -- | Matthew N.
