Looks like I'm having problems with IRQs of a PCI device. /proc/interrupts give : CPU0 16: 554 IPIC Level i2c-mpc 17: 11 IPIC Level i2c-mpc 18: 134 IPIC Level ath 19: 1557 IPIC Level serial 21: 341 IPIC Level mpc83xx_spi 38: 0 IPIC Level ehci_hcd:usb1 BAD: 2 I wonder if the IRQ number should match the vector of the datasheet ... giving : 14 -> I2C1 15 -> I2C2 16 -> SPI 38 -> USB DR The "ath" is a PCI Ath5k WiFi module connected to IRQ1, i.e. mapped to vector 17. Are the IRQ numbers shifted/mapped/scrambled in any way ? Can anyone shed some light on this ?
