#11670 new defect

Insufficient numbers of IRQs

Reported by: anonymous Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: kernel Version: Trunk
Keywords: Cc: info@…


Platform Ralink MIPS RT3050F

gpio_to_irq returned 54 for GPIO 14 where max number is defined in:


to 48.

Please increase NR_IRQS to 96 to get GPIO&IRQ working.
Should be the same on all Ralink MIPS

Tested with 96 - GPIO&IRQ is working fine
