Hi Marcel, > Attached a patch to support interrupt sharing with fast handlers. It's > pretty much copied from ia64. Please review. Looks fine.

I'll give your patch a run tonight. > With these changes, vmstat -i shows: > > imac% vmstat -i > interrupt total rate > irq19: 102984 2 > irq27: 3 0 > irq28: 1 0 > irq40: 1 0 > irq41: 25400 0 > Total 128389 2 > > I think this is the same as before, but can't really test right now.
