hi,
I have sysKonnect 1gb card integrated on the mobo after working several hours I
start to get
slowdowns.. no errors in ifconfig, no reconfiguration of 1g... nothing seems
wrong,
but the ping to this machine becomes from 8 ms to 200ms..
I can feel the lag, download speed can become more than ~20-30 mbps
any ideas what can be the problem
dmesg
eth0: network connection up using port A
speed: 1000
autonegotiation: yes
duplex mode: full
flowctrl: symmetric
role: master
irq moderation: disabled
scatter-gather: enabled

I think this happend from the time I tried to use irq moderation
i.e. options sk98lin Moderation=Dynamic,Dynamic
but as u see this is no more active...(box was restarted of cource several
times)
when I test it with : watch -n1 cat /proc/interrupts
I expect to see around ~10000 irq/s (~120mb/s), but it tops ~2000 irq/s
afaik when the card was in irq moderation mode it issues ~2000irq/s,
so is there any chance that the card memorized the configuration
and still act like it has to be moderated...?!?!
very strange...
