Hi,
Upgrading the kernel on our HS20 blades resulted in their SoL (serial over LAN) connection being broken. The disconnection happens when eth0 (the interface involved in SoL) is brought up during the boot sequence. If I later "ip link set eth0 down", then the connection is restored, but "ip link set eth0 up" breaks it again on 3.2. ethtool -a, -c, -g, -k and -u show no difference; ethtool -i on the 2.6.32 kernel reports:
driver: tg3 version: 3.116 firmware-version: 5704s-v3.38, ASFIPMIs v2.47 bus-info: 0000:05:01.0
In the 3.2 kernel the driver version is 3.121. In the output of lspci -vv only the Interrupt line shows variability. I'd be grateful for any workaround suggestion; I understand that is't not easy given the lack of information about the SoL implementation, but maybe somebody can guess what changed in the driver which could affect it this way. -- Regards, Feri.
