I don't have -mm7 handy currently (but at the moment it compiles again) but= I=20 attached the contents of /proc/interrupts of 2.4.10 (the system I currently= =20 run) and 2.5.70-mm8 again. As you can see there, the -mm8 code does not assign more than 16 interrupt= =20 sinks but the 2.4.10 (and if I remember correctly -mm7, too) has 22. Perhap= s=20 even more problematic is that -mm8 seems not to use level-triggered=20 interrupts...! I could try to revert some IRQ or APIC changes if someone could tell me whi= ch=20 Changeset may have caused that...
