Broadcom BCM5720 rx_frame_too_long_errors issue

Post by oaa » 2023/05/23 14:06:15

This post refers to a problem with Broadcom BCM5720. The distro is redhat 6.3 but I could not create a post in 6.3 section.
The faulty server is a Dell PowerEdge R720 and the kernel is 2.6.32-279.el6.i686.
I experience a high rate of "rx_frame_too_long_errors" (result of ethtool -S) when connecting the Dell PowerEdge R720 to the LAN.
When connecting a Windows PC no error is encountered!!!
The driver module is "tg3, version: 3.122"
Did someone encounter such a problem ?

Thank you

CentOS 6 died at the end of 2020 and has not seen any updates since. The forum section for CentOS 6 was closed and made readonly about 6 months later.

Worse, 6.3 is from 2012 so you have an unpatched machine there that has 11 years of security updates missing and also an old kernel that knows nothing about any hardware that has been released in the last 11 years. It also has none of the bug fixes released in the last 11 years.

I would recommend that your first step should be to point your yum repos in /etc/yum.repos.d/ to - there may even be a CentOS-Vault.repo file there that you can enable. Update your whole system to 6.10 which was the last ever release of CentOS 6. Once this is done you should be running the most recent kernel for CentOS 6 and have support and fixes for all the hardware that was introduced after 2012!

After that you need to seriously look at replacing CentOS 6 with something that is supported. I'd not bother with CentOS 7 as that also dies in about 1 year so probably isn't worth looking at. Red Hat then cancelled CentOS 8 and all future releases so if you are looking for a RHEL clone like CentOS then you need to look at one of the other rebuilds like Rocky/Alma/OEL.

The latest and last CentOS 6 kernel is kernel-2.6.32-754.35.1.el6.x86_64 so over 500 revisions newer than yours.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.
