Hi Wolfgang, in the process of preparing to merge rtdm_irq_enable into rtdm_irq_request I would like to check if the attached patch is ok, thus we could finally drop rtdm_irq_enable once the API is refactored. Please check carefully when the first IRQs may happen and what the handler expects to be initialised! SJA1000 /should/ be ok as it works with shared IRQs, but MSCAN does not (why, BTW?) and /may/ stumble.
