Yup. My ethernet card (a 3c900) and USB controller share IRQ 9. This
worked under 2.1.122 but is broken under 2.1.123 and 2.1.124.
I have attached mptable and ELCR output from 2.1.124. The output under
2.1.122 is the same except that the /proc/interrupts entry for IRQ 9
actually shows interrupts received (on both CPUs).
Thanks,
