Regarding eth0 (ftgmac100): transmit queue 0 timed out

[Mohammed.Habeeb ISV]

Hi All,

We see below backtrace on our runBmc board. And networking does not work on eth0.
No DHCP and static IP address can work. Pings and ARP fails, no packets received seen running tcpdump.
Using 2.7 version of openBmc. Please let me know if there is a known fix or patch for this.

FYI ..We tried openBmc 2.9 version. It can work fine.

Attached is the complete backtrace.

Thanks
