OK, next question, to all em users: If your em device is using a shared interrupt, and you are NOT experiencing timeout problems when using this device, please let me know: dalki# vmstat -i interrupt total rate irq4: sio0 2071 0 irq6: fdc0 10 0 irq14: ata0 47 0 irq20: ahd0 21755 4 irq23: em0 124751 23 <-- not a shared interr= upt irq24: ahd1 15 0 cpu0: timer 10453509 1999 Total 10602158 2027 tyan# vmstat -i interrupt total rate irq14: ata0 58 0 irq16: em0 fxp1 332832 851 <-- shared interrupt irq18: fxp0 973 2 irq19: atapci1 132883 339 cpu0: timer 774308 1980 cpu1: timer 777136 1987 Total 2018190 5161 So far all of the em problems I have seen involve shared interrupts, and conversely all em systems I have seen that do not have timeout problems are not shared.
