Hi!
having switched to 2.6.0-t3 to test some of the new features, I noticed more framedrops from bttv. sometimes the system feels a little sluggish, although i expected the opposite.
trying to track down the "problem" I stumbled across this:
jens@maniac:/usr/src/linux$ cat /proc/interrupts CPU0 CPU1 0: 91133739 29 IO-APIC-edge timer 1: 43765 1 IO-APIC-edge i8042 2: 0 0 XT-PIC cascade 4: 774189 0 IO-APIC-edge serial 5: 9337660 1 IO-APIC-level ohci1394, uhci-hcd, uhci-hcd 8: 4 0 IO-APIC-edge rtc 9: 15340458 1 IO-APIC-level Ensoniq AudioPCI, eth1 10: 1233326 5 IO-APIC-level ide3, eth0 11: 21436308 1 IO-APIC-level nvidia, bttv0 14: 884901 0 IO-APIC-edge ide0 15: 126 2 IO-APIC-edge ide1 NMI: 0 0 LOC: 91137709 91138393 ERR: 0 MIS: 12
irqs seem not to be distributed between cpus, having one to handle all (even while building kernel on both cpus (according to gkrell), the numbers for the second cpu don't change.
i could post any needed information (hopefully). The bootup process did not show anything raising questions to me.
any hints?
