Re: PROBLEM: Network sky2 Module

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

i'm experiencing this problem myself. i have 2 servers, one using X86_64 kernel version 2.6.23-rc5 on a 100Mbit network and one with i386 kernel version 2.6.23-rc6 on a 1Gbit network.
They both have this issue with the sky2 network device driver whereby the device would stop working and need to be brought down and back up.
On the X86_64 kernel on a 100Mbit network, this is a very occasional thing, while on the i386 kernel on a 1Gbit network the device only works for a few minutes at a time. If i set the MTU to 7200 then the device seems to stay functional, but then i see long delays when it's talking to 100Mbit devices with standard 1500 MTU that are outside of its LAN segment. 

This last might be an artifact caused by the firewall, i dunno.

[2.] Full description of the problem/report:
hw csum failure appears in syslog and sometimes, under heavy network utilization, with NFS-Daemon the Network Device totally fails. Then no Network Access is possible. Reboot is not required but i must restart the Network with the following commands: "ifdown eth0" and "rmmod sky2", then "insmod sky2" and "ifup eth0".
